test patch tried

adilger,

  I find the OBD_FAIL_TIMEOUT doesn't wait the specified seconds before it
wakes
up again. And here I tried fixed this (checking cfs_schedule_timeout() return
value which is the remaining jiffies till to the timeout value, as the patch
shows).

  And I applied OBD_FAIL_TIMEOUT both before the "spin_lock(xxx)" and before
"ptlrpc_free_committed(imp)" (as the patch to ptlrpc/client.c shows), both case

do not hit the failure case. :(

  Any more suggestions to hit it?
