Revision ca64cae96037de16e4af92678814f5d4bf0c1c65 authored by NeilBrown on 21 November 2012, 05:33:40 UTC, committed by NeilBrown on 21 November 2012, 22:14:13 UTC
commit 9e44476851e91c86c98eb92b9bc27fb801f89072
MD: raid5 avoid unnecessary zero page for trim
change raid5 to clear R5_Discard when the complete request is
handled rather than when submitting the per-device discard request.
However it did not clear R5_Discard for the parity device.
This means that if the stripe_head was reused before it expired from
the cache, the setting would be wrong and a hang would result.
Also if the R5_Uptodate bit happens to be set, R5_Discard again
won't be cleared. But R5_Uptodate really should be clear at this point.
So make sure R5_Discard is cleared in all cases, and clear
R5_Uptodate when a 'discard' completes.
