From: Joseph Qi <joseph.qi@xxxxxxxxxx>
Subject: ocfs2: fix brelse warning if ocfs2_direct_IO_get_blocks failed
In ocfs2_direct_IO_write, if ocfs2_direct_IO_get_blocks failed, the
di_bh will be used again in unlikely branch, and this will hit a warning
"VFS: brelse: Trying to free free buffer" when jbd2 do checkpoint.
Fix this issue by setting di_bh to NULL after brelse.
