* xfs: check quota files for unwritten extentsDarrick J. Wong2022-11-161-2/+4
| | | | | | | Teach scrub to flag quota files containing unwritten extents. Signed-off-by: Darrick J. Wong <djwong@kernel.org> Reviewed-by: Dave Chinner <dchinner@redhat.com>
* xfs: fix return code when fatal signal encountered during dquot scrubDarrick J. Wong2022-11-161-1/+1
| | | | | | | | | | If the scrub process is sent a fatal signal while we're checking dquots, the predicate for this will set the error code to -EINTR. Don't then squash that into -ECANCELED, because the wrong errno turns up in the trace output. Signed-off-by: Darrick J. Wong <djwong@kernel.org> Reviewed-by: Dave Chinner <dchinner@redhat.com>

* xfs: fix quotaoff mutex usage now that we don't support disabling itDarrick J. Wong2021-12-211-2/+2
| | | | | | | | | | | | | | | | Prior to commit 40b52225e58c ("xfs: remove support for disabling quota accounting on a mounted file system"), we used the quotaoff mutex to protect dquot operations against quotaoff trying to pull down dquots as part of disabling quota. Now that we only support turning off quota enforcement, the quotaoff mutex only protects changes in m_qflags/sb_qflags. We don't need it to protect dquots, which means we can remove it from setqlimits and the dquot scrub code. While we're at it, fix the function that forces quotacheck, since it should have been taking the quotaoff mutex. Signed-off-by: Darrick J.

* xfs: convert xfs_sb_version_has checks to use mount featuresDave Chinner2021-08-191-1/+1
| | | | | | | | | | | | | | | | | | | | | This is a conversion of the remaining xfs_sb_version_has..(sbp) checks to use xfs_has_..(mp) feature checks. This was largely done with a vim replacement macro that did: :0,$s/xfs_sb_version_has\(.*\)&\(.*\)->m_sb/xfs_has_\1\2/g<CR> A couple of other variants were also used, and the rest touched up by hand. $ size -t fs/xfs/built-in.a text data bss dec hex filename before 1127533 311352 484 1439369 15f689 (TOTALS) after 1125360 311352 484 1437196 15ee0c (TOTALS) Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Darrick J.

* xfs: remove the active vs running quota differentiationChristoph Hellwig2021-08-061-1/+1
| | | | | | | | | | | | These only made a difference when quotaoff supported disabling quota accounting on a mounted file system, so we can switch everyone to use a single set of flags and helpers now. Note that the *QUOTA_ON naming for the helpers is kept as it was the much more commonly used one.

* xfs: get rid of the ip parameter to xchk_setup_*Darrick J. Wong2021-04-091-3/+2
| | | | | | | | | | | Now that the scrub context stores a pointer to the file that was used to invoke the scrub call, the struct xfs_inode pointer that we passed to all the setup functions is no longer necessary. This is only ever used if the caller wants us to scrub the metadata of the open file. Signed-off-by: Darrick J.

* xfs: fix dquot scrub loop cancellationDarrick J. Wong2021-03-251-2/+4
| | | | | | | | | | | When xchk_quota_item figures out that it needs to terminate the scrub operation, it needs to return some error code to abort the loop, but instead it returns zero and the loop keeps running. Fix this by making it use ECANCELED, and fix the other loop bailout condition check at the bottom too. Signed-off-by: Darrick J. Wong <djwong@kernel.org> Reviewed-by: Christoph Hellwig <hch@lst.de>
* xfs: create xfs_dqtype_t to represent quota typesDarrick J. Wong2020-07-281-4/+4
| | | | | | | | | | | | | | Create a new type (xfs_dqtype_t) to represent the type of an incore dquot (user, group, project, or none). Rename the incore dquot's dq_flags field to q_type. This allows us to replace all the "uint type" arguments to the quota functions with "xfs_dqtype_t type", to make it obvious when we're passing a quota type argument into a function.

* xfs: add missing early termination checks to record scrubbing functionsDarrick J. Wong2019-11-061-0/+7
| | | | | | | | | | | | | | | Scrubbing directories, quotas, and fs counters all involve iterating some collection of metadata items. The per-item scrub functions for these three are missing some of the components they need to be able to check for a fatal signal and terminate early. Per-item scrub functions need to call xchk_should_terminate to look for fatal signals, and they need to check the scrub context's corruption flag because there's no point in continuing a scan once we've decided the data structure is bad. Add both of these where missing. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Christoph Hellwig <hch@lst.de>
