Amir Goldstein 8cbc48b460 overlay: Regression test for deadlock on directory ioctl
Overlayfs added the ability to set inode flags (e.g. chattr +i) in
kernel 5.10 by commit 61536bed2149 ("ovl: support [S|G]ETFLAGS and
FS[S|G]ETXATTR ioctls for directories").
Icenowy Zheng reported [1] a regression in that commit that causes
a deadlock when setting inode flags on lower dir.

The regression was fixed by commit b854cc659dcb ("ovl: avoid deadlock
on directory ioctl") and applied to kernel 5.10.15.
