Merge tag 'vfs-6.15-rc3.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs fixes from Christian Brauner:

 - Fix NULL pointer dereference in virtiofs

 - Fix slab OOB access in hfs/hfsplus

 - Only create /proc/fs/netfs when CONFIG_PROC_FS is set

 - Fix getname_flags() to initialize pointer correctly

 - Convert dentry flags to enum

 - Don't allow datadir without lowerdir in overlayfs

 - Use namespace_{lock,unlock} helpers in dissolve_on_fput() instead of
   plain namespace_sem so unmounted mounts are properly cleaned up

 - Skip unnecessary ifs_block_is_uptodate check in iomap

 - Remove an unused forward declaration in overlayfs

 - Fix devpts uid/gid handling after converting to the new mount api

 - Fix afs_dynroot_readdir() to not use the RCU read lock

 - Fix mount_setattr() and open_tree_attr() to not pointlessly do path
   lookup or walk the mount tree if no mount option change has been
   requested
