Since btrfs_bio always contains the extra space for the tgtdev_map and raid_maps it's pointless to make the assignment iff specific conditions are met. Instead, always assign the pointers to their correct value at allocation time. To accommodate this change also move code a bit in __btrfs_map_block so that btrfs_bio::stripes array is always initialized before the raid_map, subsequently move the call to sort_parity_stripes in the 'if' building the raid_map, retaining the old behavior. To better understand the change, there are 2 aspects to this: 1. The original code is harder to grasp because the calculations for initializing raid_map/tgtdev ponters are apart from the initial allocation of memory. Having them predicated on 2 separate checks doesn't help that either... So by moving the initialisation in alloc_btrfs_bio puts everything together. 2. tgtdev/raid_maps are now always initialized despite sometimes they might be equal i.e __btrfs_map_block_for_discard calls alloc_btrfs_bio with tgtdev = 0 but their usage should be predicated on external checks i.e. just because those pointers are non-null doesn't mean they are valid per-se. And actually while taking another look at __btrfs_map_block I saw a discrepancy: Original code initialised tgtdev_map if the following check is true: if (dev_replace_is_ongoing && dev_replace->tgtdev != NULL) However, further down tgtdev_map is only used if the following check is true: if (dev_replace_is_ongoing && dev_replace->tgtdev != NULL && need_full_stripe(op)) e.g. the additional need_full_stripe(op) predicate is there.

Since BTRFS uses a private bdi it makes sense to create a link to this bdi under /sys/fs/btrfs/<UUID>/bdi. This allows size of read ahead to be controlled. Without this patch it's not possible to uniquely identify which bdi pertains to which btrfs filesystem in the case of multiple btrfs filesystems. It's fine to simply call sysfs_remove_link without checking if the link indeed has been created. The call path sysfs_remove_link kernfs_remove_by_name kernfs_remove_by_name_ns will simply return -ENOENT in case it doesn't exist. Signed-off-by:

Now that btrfs_io_bio have access to btrfs_device we can safely increment the device corruption counter on error. There is one notable exception - repair bios for raid. Since those don't go through the normal submit_stripe_bio callpath but through raid56_parity_recover thus repair bios won't have their device set. Scrub increments the corruption counter for checksum mismatch as well but does not call this function. Link: https://lore.kernel.org/linux-btrfs/4857863.FCrPRfMyHP@liv/ Reviewed-by:

btrfs_map_bio ensures that all submitted bios to devices have valid btrfs_device::bdev so this check can be removed from btrfs_end_bio. This check was added in june 2012 597a60fa ("Btrfs: don't count I/O statistic read errors for missing devices") but then in October of the same year another commit de1ee92a ("Btrfs: recheck bio against block device when we map the bio") started checking for the presence of btrfs_device::bdev before actually issuing the bio.

Only failure that get_state_failrec can get is if there is no failure for the given address. There is no reason why the function should return a status code and use a separate parameter for returning the actual failure rec (if one is found).

When syncing the log, we used to update the log root tree without holding neither the log_mutex of the subvolume root nor the log_mutex of log root tree. We used to have two critical sections delimited by the log_mutex of the log root tree, so in the first one we incremented the log_writers of the log root tree and on the second one we decremented it and waited for the log_writers counter to go down to zero. This was because the update of the log root tree happened between the two critical sections. The use of two critical sections allowed a little bit more of parallelism and required the use of the log_writers counter, necessary to make sure we didn't miss any log root tree update when we have multiple tasks trying to sync the log in parallel. However after commit 06989c79 ("Btrfs: fix race updating log root item during fsync") the log root tree update was moved into a critical section delimited by the subvolume's log_mutex. Later another commit moved the log tree update from that critical section into the second critical section delimited by the log_mutex of the log root tree. Both commits addressed different bugs. The end result is that the first critical section delimited by the log_mutex of the log root tree became pointless, since there's nothing done between it and the second critical section, we just have an unlock of the log_mutex followed by a lock operation. This means we can merge both critical sections, as the first one does almost nothing now, and we can stop using the log_writers counter of the log root tree, which was incremented in the first critical section and decremented in the second criticial section, used to make sure no one in the second critical section started writeback of the log root tree before some other task updated it. So just remove the mutex_unlock() followed by mutex_lock() of the log root tree, as well as the use of the log_writers counter for the log root tree. This patch is part of a series that has the following patches: 1/4 btrfs: only commit the delayed inode when doing a full fsync 2/4 btrfs: only commit delayed items at fsync if we are logging a directory 3/4 btrfs: stop incremening log_batch for the log root tree when syncing log 4/4 btrfs: remove no longer needed use of log_writers for the log root tree After the entire patchset applied I saw about 12% decrease on max latency reported by dbench. The test was done on a qemu vm, with 8 cores, 16Gb of ram, using kvm and using a raw NVMe device directly (no intermediary fs on the host).

We are incrementing the log_batch atomic counter of the root log tree but we never use that counter, it's used only for the log trees of subvolume roots. We started doing it when we moved the log_batch and log_write counters from the global, per fs, btrfs_fs_info structure, into the btrfs_root structure in commit 7237f183 ("Btrfs: fix tree logs parallel sync"). So just stop doing it for the log root tree and add a comment over the field declaration so inform it's used only for log trees of subvolume roots.

When logging an inode we are committing its delayed items if either the inode is a directory or if it is a new inode, created in the current transaction. We need to do it for directories, since new directory indexes are stored as delayed items of the inode and when logging a directory we need to be able to access all indexes from the fs/subvolume tree in order to figure out which index ranges need to be logged. However for new inodes that are not directories, we do not need to do it because the only type of delayed item they can have is the inode item, and we are guaranteed to always log an up to date version of the inode item: *) for a full fsync we do it by committing the delayed inode and then copying the item from the fs/subvolume tree with copy_inode_items_to_log(); *) for a fast fsync we always log the inode item based on the contents of the in-memory struct btrfs_inode. We guarantee this is always done since commit e4545de5 ("Btrfs: fix fsync data loss after append write"). So stop running delayed items for a new inodes that are not directories, since that forces committing the delayed inode into the fs/subvolume tree, wasting time and adding contention to the tree when a full fsync is not required. We will only do it in case a fast fsync is needed. This patch is part of a series that has the following patches: 1/4 btrfs: only commit the delayed inode when doing a full fsync 2/4 btrfs: only commit delayed items at fsync if we are logging a directory 3/4 btrfs: stop incremening log_batch for the log root tree when syncing log 4/4 btrfs: remove no longer needed use of log_writers for the log root tree After the entire patchset applied I saw about 12% decrease on max latency reported by dbench.

Commit 2c2c452b ("Btrfs: fix fsync when extend references are added to an inode") forced a commit of the delayed inode when logging an inode in order to ensure we would end up logging the inode item during a full fsync. By committing the delayed inode, we updated the inode item in the fs/subvolume tree and then later when copying items from leafs modified in the current transaction into the log tree (with copy_inode_items_to_log()) we ended up copying the inode item from the fs/subvolume tree into the log tree. Logging an up to date version of the inode item is required to make sure at log replay time we get the link count fixup triggered among other things (replay xattr deletes, etc). The test case generic/040 from fstests exercises the bug which that commit fixed. However for a fast fsync we don't need to commit the delayed inode because we always log an up to date version of the inode item based on the struct btrfs_inode we have in-memory. We started doing this for fast fsyncs since commit e4545de5 ("Btrfs: fix fsync data loss after append write"). So just stop committing the delayed inode if we are doing a fast fsync, we are only wasting time and adding contention on fs/subvolume tree.

The ids are in a shared pool of size 1<<20. The ids are assigned to live subvolumes, ie. the root structure exists in memory (eg. after creation or after the root appears in some path). The pool could be exhausted if the numbers are not reclaimed fast enough, after subvolume deletion or if other system component uses the anon block devices. [WORKAROUND] Since it's not possible to completely solve the problem, we can only minimize the time the id is allocated to a subvolume root. Firstly, we can reduce the use of anon_dev by trees that are not subvolume roots, like data reloc tree. This patch will do extra check on root objectid, to skip roots that don't need anon_dev. Currently it's only data reloc tree and orphan roots. Reported-by:
