While the FALLOC_FL_NO_HIDE_STALE value has been registered, it has
always been rejected by vfs_fallocate before making it into
blkdev_fallocate because it isn't in the supported mask.

Applied to the vfs.fallocate branch of the vfs/vfs.git tree.
Patches in the vfs.fallocate branch should appear in linux-next soon.

new review to the original patch series allowing us to drop it.

It's encouraged to provide Acked-bys and Reviewed-bys even though the
patch has now been applied. If possible patch trailers will be updated.

Note that commit hashes shown below are subject to change due to rebase,
trailer updates or similar. If in doubt, please check the listed branch.
