[GIT PULL] vfs fixes

[Christian Brauner <brauner@kernel.org>]

Hey Linus,

I was sent a bug fix for the backing file rework that relied on the
overlayfs pull request. The vfs.fixes branch used an earlier mainline
commit as base. So I thought how to resolve this and my solution was to
create a new ovl.fixes branch which contained the overlayfs changes for
v6.13 and then apply the fix on top of it. That branch was then merged
into vfs.fixes with an explanation why. Let me know if I should do this
differently next time.

/* Summary */

This contains various fixes for this cycle:

- Fix a few iomap bugs.

- Fix a wrong argument in backing file callback.

- Fix security mount option retrieval in statmount().

- Cleanup how statmount() handles unescaped options.

- Add a missing inode_owner_or_capable() check for setting write hints.

- Clear the return value in read_kcore_iter() after a successful
  iov_iter_zero().

- Fix a mount_setattr() selftest.

- Fix function signature in mount api documentation.

- Remove duplicate include header in the fscache code.

/* Testing */

gcc version 14.2.0 (Debian 14.2.0-6)
Debian clang version 16.0.6 (27+b1)

All patches have been sitting in linux-next.
No build failures or warnings were observed.
