[merged] ocfs2-do-not-log-twice-error-messages.patch removed from -mm tree

[akpm@xxxxxxxxxxxxxxxxxxxx]

The patch titled
     Subject: ocfs2: do not log twice error messages
has been removed from the -mm tree.  Its filename was
     ocfs2-do-not-log-twice-error-messages.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>
Subject: ocfs2: do not log twice error messages

'o2hb_map_slot_data' and 'o2hb_populate_slot_data' are called from only
one place, in 'o2hb_region_dev_write'.  Return value is checked and
'mlog_errno' is called to log a message if it is not 0.

So there is no need to call 'mlog_errno' directly within these functions. 
This would result on logging the message twice.
