Subject: [PATCH 6/6] move XFS_BMAP_SANITY_CHECK out of line
Date: Mon, 15 Sep 2008 02:47:03 +0200 [thread overview]
Message-ID: <20080915004703.GG12213@lst.de> (raw)
[-- Attachment #1: xfs-move-XFS_BMAP_SANITY_CHECK-out-of-line --]
[-- Type: text/plain, Size: 2628 bytes --]
Move the XFS_BMAP_SANITY_CHECK macro out of line and make it a properly typed
function. Also pass the xfs_buf for the btree block instead of just the btree
block header, as we will need some additional information for it to implement
CRC checking of btree blocks.
