When swalloc is specified as a mount option, allocations are supposed to be aligned to the stripe width rather than the stripe unit of the underlying filesystem. However, it does not do this. What the implementation does is round up the allocation size to a stripe width, hence ensuring that all allocations span a full stripe width. It does not, however, ensure that that allocation is aligned to a stripe width, and hence the allocations can span multiple underlying stripes and so still see RMW cycles for things like direct IO on MD RAID. So, if the swalloc mount option is set, change the allocation alignment in xfs_bmap_btalloc() to use the stripe width rather than the stripe unit. Signed-off-by:

The xfsbdstrat helper is a small but useless wrapper for xfs_buf_iorequest that handles the case of a shut down filesystem. Most of the users have private, uncached buffers that can just be freed in this case, but the complex error handling in xfs_bioerror_relse messes up the case when it's called without a locked buffer. Remove xfsbdstrat and opencode the error handling in the callers. All but one can simply return an error and don't need to deal with buffer state, and the one caller that cares about the buffer state could do with a major cleanup as well, but we'll defer that to later.

The function xfs_bmap_isaeof() is used to indicate that an allocation is occurring at or past the end of file, and as such should be aligned to the underlying storage geometry if possible. Commit 27a3f8f2 ("xfs: introduce xfs_bmap_last_extent") changed the behaviour of this function for empty files - it turned off allocation alignment for this case accidentally. Hence large initial allocations from direct IO are not getting correctly aligned to the underlying geometry, and that is cause write performance to drop in alignment sensitive configurations. Fix it by considering allocation into empty files as requiring aligned allocation again. Signed-off-by:

Otherwise, those dquots refcount is non-zero due to the user dquot might refer to them as hint(s). Hence, above operation cause an infinite loop at xfs_qm_dquot_walk() while trying to purge dquot cache. This problem has been around since Linux 3.4, it was introduced by: [ b84a3a96 xfs: remove the per-filesystem list of dquots ] Originally we will release the group dquot pointers because the user dquots maybe carrying around as a hint via xfs_qm_detach_gdquots(). However, with above change, there is no such work to be done before purging group/project dquot cache. In order to solve this problem, this patch introduces a special routine xfs_qm_dqpurge_hints(), and it would release the group/project dquot pointers the user dquots maybe carrying around as a hint, and then it will proceed to purge the user dquot cache if requested.

This loop in xfs_growfs_data_private() is incorrect for V4 superblocks filesystems: for (bucket = 0; bucket < XFS_AGFL_SIZE(mp); bucket++) agfl->agfl_bno[bucket] = cpu_to_be32(NULLAGBLOCK); For V4 filesystems, we don't have a agfl header structure, and so XFS_AGFL_SIZE() returns an entire sector's worth of entries, which we then index from an offset into the sector. Hence: buffer overrun. This problem was introduced in 3.10 by commit 77c95bba ("xfs: add CRC checks to the AGFL") which changed the AGFL structure but failed to update the growfs code to handle the different structures. Fix it by using the correct offset into the buffer for both V4 and V5 filesystems. Cc: <stable@vger.kernel.org> Signed-off-by:

PTE_PROT_NONE means that a pte is present but does not have any read/write attributes. However, setting the memory type like pgprot_writecombine() is allowed and such bits overlap with PTE_PROT_NONE. This causes mmap/munmap issues in drivers that change the vma->vm_pg_prot on PROT_NONE mappings.

The current generic parser assumes blindly that the volume and mute amps are found in the aamix node itself. But on some codecs, typically Analog Devices ones, the aamix amps are separately implemented in each leaf node of the aamix node, and the current driver can't establish the correct amp controls. This is a regression compared with the previous static quirks. This patch extends the search for the amps to the leaf nodes for allowing the aamix controls again on such codecs. In this implementation, I didn't code to loop through the whole paths, since usually one depth should suffice, and we can't search too deeply, as it may result in the conflicting control assignments.

In order to find I2C devices in the device tree, the platform nodes have to be known by the I2C core. This requires setting the dev.of_node parameter of the adapter. Signed-off-by:
