Merge tag 'vfs-7.2-rc1.kfunc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull bpf filesystem kfunc fix from Christian Brauner:
 "The bpf_set_dentry_xattr() and bpf_remove_dentry_xattr() kfuncs locked
  the inode of the supplied dentry without checking whether the dentry
  is negative.

  Passing a negative dentry (e.g., from security_inode_create) caused a
  NULL pointer dereference. Negative dentries now fail with EINVAL. The
  WARN_ON(!inode) in the bpf xattr permission helpers is dropped as well
  since it could be triggered the same way, amounting to a denial of
  service on systems with panic_on_warn enabled"

* tag 'vfs-7.2-rc1.kfunc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
  bpf: fix crash in bpf_[set|remove]_dentry_xattr for negative dentries
