[PATCH 0/4][RFC] remove duplicated check from ext4, xfs, btrfs, and ocfs2

Hi all,

This patch series tries to remove a sanity check in fallocate from specific
filesystems because vfs has already checked it.

I am not very familiar with why we need to do this duplicated check.  Please let
me know if I miss something.

Regards,
						- Zheng
