[GIT PULL for v7.1] vfs fixes

[Christian Brauner <brauner@kernel.org>]

Hey Linus,

/* Summary */

This contains a fixes for the current development cycle. Note that AI
related review sometimes delays fixes a bit because we find more fixes
for the fixes. I might try and send smaller but more fixes PRs if this
trend keeps up.

- Fix various netfslib bugs

- Fix an out-of-bounds write when listing idmappings.

- Fix the return values in jfs_mkdir() and orangefs_mkdir().

- Fix a writeback writeback array overflow in fuse.

- Fix a forced iversion increment on lazytime timestamp updates

- Reject a negative timeval component in kern_select().

- Fix error return when vfs_mkdir() fails in the cachefiles code.

- Fix wrong error code returned for pidns ioctls.
