Subject[GIT PULL] fs mapping helpers update
Date
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@gitolite.kernel.org:pub/scm/linux/kernel/git/brauner/linux tags/fs.idmapped.helpers.v5.13

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.

/* 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.)

Please consider pulling these changes from the signed fs.idmapped.helpers.v5.13 tag.
