Merge tag 'vfs-6.16-rc7.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs fixes from Christian Brauner:

 - Fix a memory leak in fcntl_dirnotify()

 - Raise SB_I_NOEXEC on secrement superblock instead of messing with
   flags on the mount

 - Add fsdevel and block mailing lists to uio entry. We had a few
   instances were very questionable stuff was added without either block
   or the VFS being aware of it

 - Fix netfs copy-to-cache so that it performs collection with
   ceph+fscache

 - Fix netfs race between cache write completion and ALL_QUEUED being
   set

 - Verify the inode mode when loading entries from disk in isofs

 - Avoid state_lock in iomap_set_range_uptodate()

 - Fix PIDFD_INFO_COREDUMP check in PIDFD_GET_INFO ioctl

 - Fix the incorrect return value in __cachefiles_write()
