xfs: remove struct xfs_attr_shortform sparse complains about struct xfs_attr_shortform because it embeds a structure with a variable sized array in a variable sized array. Given that xfs_attr_shortform is not a very useful structure, and the dir2 equivalent has been removed a long time ago, remove it as well. Provide a xfs_attr_sf_firstentry helper that returns the first xfs_attr_sf_entry behind a xfs_attr_sf_hdr to replace the structure dereference.

xfs: don't load local xattr values during scrub Local extended attributes store their values within the same leaf block. There's no header for the values themselves, nor are they separately checksummed. Hence we can save a bit of time in the attr scrubber by not wasting time retrieving the values. Regrettably, shortform attributes do not set XFS_ATTR_LOCAL so this offers us no advantage there, but at least there are very few attrs in that case. Signed-off-by: Darrick J.

xfs: replace xfs_sb_version checks with feature flag checks Convert the xfs_sb_version_hasfoo() to checks against mp->m_features. Checks of the superblock itself during disk operations (e.g. in the read/write verifiers and the to/from disk formatters) are not converted - they operate purely on the superblock state. Everything else should use the mount features. Large parts of this conversion were done with sed with commands like this: for f in `git grep -l xfs_sb_version_has fs/xfs/*.c`; do sed -i -e 's/xfs_sb_version_has\(.*\)(&\(.*\)->m_sb)/xfs_has_\1(\2)/' $f done With manual cleanups for things like "xfs_has_extflgbit" and other little inconsistencies in naming.

xfs: online scrub needn't bother zeroing its temporary buffer The xattr scrubber functions use the temporary memory buffer either for storing bitmaps or for testing if attribute value extraction works. The bitmap code always zeroes what it needs and the value extraction sets the buffer contents, so it's not necessary to waste CPU time zeroing on allocation. Note that while we never read the contents that the attr value extraction function sets, we do need to call it to check the remote attribute header and CRCs to check for corruption. A flame graph analysis showed that we were spending 7% of a xfs_scrub run (the whole program, not just the attr scrubber itself) allocating and zeroing 64k segments needlessly.

xfs: only allocate memory for scrubbing attributes when we need it In examining a flame graph of time spent running xfs_scrub on various filesystems, I noticed that we spent nearly 7% of the total runtime on allocating a zeroed 65k buffer for every SCRUB_TYPE_XATTR invocation. We do this even if none of the attribute values were anywhere near 64k in size, even if there were no attribute blocks to check space on, and even if it just turns out there are no attributes at all. Therefore, rearrange the xattr buffer setup code to support reallocating with a bigger buffer and redistribute the callers of that function so that we only allocate memory just prior to needing it, and only allocate as much as we need. If we can't get memory with the ILOCK held we'll bail out with EDEADLOCK which will allocate the maximum memory. Signed-off-by: Darrick J.

xfs: pass inode number to xfs_scrub_ino_set_{preen,warning} There are two ways to scrub an inode -- calling xfs_iget and checking the raw inode core, or by loading the inode cluster buffer and checking the on-disk contents directly. The second method is only useful if _iget fails the verifiers; when this is the case, sc->ip is NULL and calling the tracepoint will cause a system crash. Therefore, pass the raw inode number directly into the _preen and _warning functions. Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Darrick J.
