This test is based on generic/273, a regression test for commit

9a3a5da xfs: check for stale inode before acquiring iflock on push

On unpatched kernel, rm processes would hang.

v2: Address Dave's comments
 - don't check return value of mkdir
 - don't cd to origin dir
 - don't calculate fs size, already have fs size
 - use $XFS_IO_PROG instead of dd
 - remove leading "_" from local vars
 - call _supported_fs etc. functions before any local functions
 - set status=0 before exit
