Subject: [PATCH 05/16] xfs: fix incorrect test in
|
||
|
|
xfs_alloc_ag_vextent_lastblock
|
||
|
|
|
||
|
|
Source kernel commit: 77ca1eed5a7d2bf0905562eb1a15aac76bc19fe4
|
||
|
|
|
||
|
|
When I lifted the code in xfs_alloc_ag_vextent_lastblock out of a loop,
|
||
|
|
I forgot to convert all the accesses to len to be pointer dereferences.
