From: Konstantin Khorenko <[email protected]>
At the moment XFS is not marked as ready to be mounted inside non-init
userns (see xfs_fs_type), while we previously decided to allow using XFS
inside a CT:
b86b9049ba50 ("xfs: allow to mount xfs fs inside a Container")
https://jira.sw.ru/browse/PSBM-72401
so let's mark XFS as mount-able inside non-init userns.
Fixes: b86b9049ba50 ("xfs: allow to mount xfs fs inside a Container")
https://jira.sw.ru/browse/PSBM-86369

eshatokhin@:
Used FS_VE_MOUNT as suggested by Pavel Tikhomirov (ptikhomirov@) instead
of FS_USERNS_MOUNT: it is better to allow mounts only from the init
userns of a container rather than from just any userns.
Done in the scope of https://jira.sw.ru/browse/PSBM-127830.
