Hi Linus, /* Summary */ This adds kernel-doc to all new idmapping helpers and improves their naming which was triggered by a discussion with some fs developers. Some of the names are based on suggestions by Vivek and Al. We also remove the open-coded permission checking in a few places with simple helpers. Overall this should lead to more clarity make it easier to maintain. The following changes since commit 0d02ec6b3136c73c09e7859f0d0e4e2c4c07b49b: Linux 5.12-rc4 (2021-03-21 14:56:43 -0700) are available in the Git repository at: git@xxxxxxxxxxxxxxxxxxx:pub/scm/linux/kernel/git/brauner/linux tags/fs.idmapped.helpers.v5.13 for you to fetch changes up to db998553cf11dd697485ac6142adbb35d21fff10: fs: introduce two inode i_{u,g}id initialization helpers (2021-03-23 11:15:26 +0100) /* Testing */ All patches are based on v5.12-rc4 and have been sitting in linux-next. No build failures or warnings were observed. All old and new tests are passing. ubuntu@f2-vm:~/src/git/xfstests$ sudo ./check -g idmapped FSTYP -- xfs (debug) PLATFORM -- Linux/x86_64 f2-vm 5.12.0-rc6-idmapped-cfebad8730dd #387 SMP PREEMPT Tue Apr 27 10:39:29 UTC 2021 MKFS_OPTIONS -- -f -bsize=4096 /dev/loop1 MOUNT_OPTIONS -- /dev/loop1 /mnt/scratch generic/633 files ... 27s xfs/152 files ... 68s xfs/153 files ... 36s Ran: generic/633 xfs/152 xfs/153 Passed all 3 tests /* Conflicts */ At the time of creating this PR no merge conflicts were reported from linux-next and no merge conflicts showed up doing a test-merge with current mainline. (Note, in case you care about this at all I changed my tag naming pattern simply because I ran into limitations with branch naming in git using "/" separators and I like to have a 1:1 correspondence between the branch and the tag name.)
