The AGF already has some self identifying fields (e.g. the sequence number) so we only need to add the uuid to it to identify the filesystem it belongs to. The location is fixed based on the sequence number, so there's no need to add a block number, either. Hence the only additional fields are the CRC and LSN fields. These are unlogged, so place some space between the end of the logged fields and them so that future expansion of the AGF for logged fields can be placed adjacent to the existing logged fields and hence not complicate the field-derived range based logging we currently have. Based originally on a patch from myself, modified further by Christoph Hellwig and then modified again to fit into the verifier structure with additional fields by myself. The multiple signed-off-by tags indicate the age and history of this patch. Signed-off-by:

Currently xfs_corruption_error() dumps the first 16 bytes of the buffer that is passed to it when a corruption occurs. This is not large enough to see the entire state of the header of the block that was determined to be corrupt. increase the output to 64 bytes to capture the majority of all headers in all types of metadata blocks.

Filesystems are occasionally being shut down with this error: xfs_trans_ail_delete_bulk: attempting to delete a log item that is not in the AIL. It was diagnosed to be related to the EFI/EFD commit order when the EFI and EFD are in different checkpoints and the EFD is committed before the EFI here: http://oss.sgi.com/archives/xfs/2013-01/msg00082.html The real problem is that a single bit cannot fully describe the states that the EFI/EFD processing can be in. These completion states are: EFI EFI in AIL EFD Result committed/unpinned Yes committed OK committed/pinned No committed Shutdown uncommitted No committed Shutdown Note that the "result" field is what should happen, not what does happen. The current logic is broken and handles the first two cases correctly by luck. That is, the code will free the EFI if the XFS_EFI_COMMITTED bit is *not* set, rather than if it is set. The inverted logic "works" because if both EFI and EFD are committed, then the first __xfs_efi_release() call clears the XFS_EFI_COMMITTED bit, and the second frees the EFI item. Hence as long as xfs_efi_item_committed() has been called, everything appears to be fine. It is the third case where the logic fails - where xfs_efd_item_committed() is called before xfs_efi_item_committed(), and that results in the EFI being freed before it has been committed. That is the bug that triggered the shutdown, and hence keeping track of whether the EFI has been committed or not is insufficient to correctly order the EFI/EFD operations w.r.t. the AIL. What we really want is this: the EFI is always placed into the AIL before the last reference goes away. The only way to guarantee that is that the EFI is not freed until after it has been unpinned *and* the EFD has been committed. That is, restructure the logic so that the only case that can occur is the first case. This can be done easily by replacing the XFS_EFI_COMMITTED with an EFI reference count. The EFI is initialised with it's own count, and that is not released until it is unpinned. However, there is a complication to this method - the high level EFI/EFD code in xfs_bmap_finish() does not hold direct references to the EFI structure, and runs a transaction commit between the EFI and EFD processing. Hence the EFI can be freed even before the EFD is created using such a method. Further, log recovery uses the AIL for tracking EFI/EFDs that need to be recovered, but it uses the AIL *differently* to the EFI transaction commit. Hence log recovery never pins or unpins EFIs, so we can't drop the EFI reference count indirectly to free the EFI. However, this doesn't prevent us from using a reference count here. There is a 1:1 relationship between EFIs and EFDs, so when we initialise the EFI we can take a reference count for the EFD as well. This solves the xfs_bmap_finish() issue - the EFI will never be freed until the EFD is processed. In terms of log recovery, during the committing of the EFD we can look for the XFS_EFI_RECOVERED bit being set and drop the EFI reference as well, thereby ensuring everything works correctly there as well.

When a dirty page is truncated from a file but reclaim gets to it before truncate_inode_pages(), we hit WARN_ON(delalloc) in xfs_vm_releasepage(). This is because reclaim tries to write the page, xfs_vm_writepage() just bails out (leaving page clean) and thus reclaim thinks it can continue and calls xfs_vm_releasepage() on page with dirty buffers. Fix the issue by redirtying the page in xfs_vm_writepage(). This makes reclaim stop reclaiming the page and also logically it keeps page in a more consistent state where page with dirty buffers has PageDirty set. Signed-off-by:

Enable tracking of high and low watermarks for preallocation throttling of files under quota restrictions. These values are calculated when the quota limit is read from disk or modified and cached for later use by the throttling algorithm. The high watermark specifies when preallocation is disabled, the low watermark specifies when throttling is enabled and the low free space data structure contains precalculated low free space limits to serve as input to determine the level of throttling required. Note that the low free space data structure is based on the existing global low free space data structure with the exception of using three stages (5%, 3% and 1%) rather than five to reduce the impact of xfs_dquot memory overhead.

Failed buffer readahead can leave the buffer in the cache marked with an error. Most callers that then issue a subsequent read on the buffer do not zero the b_error field out, and so we may incorectly detect an error during IO completion due to the stale error value left on the buffer. Avoid this problem by zeroing the error before IO submission. This ensures that the only IO errors that are detected those captured from are those captured from bio submission or completion.

xfs_bmap.c is a big file, and some of the related code is spread all throughout the file requiring function prototypes for static function and jumping all through the file to follow a single call path. Rearrange the code so that: a) related functionality is grouped together; and b) functions are grouped in call dependency order While the diffstat is large, there are no code changes in the patch; it is just moving the functionality around and removing the function prototypes at the top of the file. The resulting layout of the code is as follows (top of file to bottom): - miscellaneous helper functions - extent tree block counting routines - debug/sanity checking code - bmap free list manipulation functions - inode fork format manipulation functions - internal/external extent tree seach functions - extent tree manipulation functions used during allocation - functions used during extent read/allocate/removal operations (i.e. xfs_bmapi_write, xfs_bmapi_read, xfs_bunmapi and xfs_getbmap) This means that following logic paths through the bmapi code is much simpler - most of the code relevant to a specific operation is now clustered together rather than spread all over the file....

The updated speculative preallocation algorithm for handling sparse files can becomes less effective in situations with a high number of concurrent, sequential writers. The number of writers and amount of available RAM affect the writeback bandwidth slicing algorithm, which in turn affects the block allocation pattern of XFS. For example, running 32 sequential writers on a system with 32GB RAM, preallocs become fixed at a value of around 128MB (instead of steadily increasing to the 8GB maximum as sequential writes proceed). Update the speculative prealloc heuristic to base the size of the next prealloc on double the size of the preceding extent. This preserves the original aggressive speculative preallocation behavior and continues to accomodate sparse files at a slight cost of increasing the size of preallocated data regions following holes of sparse files.
