Subject: xfs: only lock the rt bitmap inode once per allocation
X-Git-Tag: v2.6.39-rc1~394^2~22
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=04e99455ea5bb17ea7c2e7bb0970168efb736242;p=pandora-kernel.git

xfs: only lock the rt bitmap inode once per allocation

Currently both xfs_rtpick_extent and xfs_rtallocate_extent call
xfs_trans_iget to grab and lock the rt bitmap inode, which results in a
deadlock since the removal of the lock recursion counters in commit

	"xfs: simplify inode to transaction joining"

Fix this by acquiring and locking the inode in xfs_bmap_rtalloc before
calling into xfs_rtpick_extent and xfs_rtallocate_extent.
