Subject: [merged] fanotify-reorganize-loop-in-fanotify_read.patch removed from -mm tree To: jack@xxxxxxx,eparis@xxxxxxxxxx,viro@xxxxxxxxxxxxxxxxxx,mm-commits@xxxxxxxxxxxxxxx From: akpm@xxxxxxxxxxxxxxxxxxxx Date: Fri, 04 Apr 2014 12:29:39 -0700 The patch titled Subject: fanotify: reorganize loop in fanotify_read() has been removed from the -mm tree. Its filename was fanotify-reorganize-loop-in-fanotify_read.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Jan Kara <jack@xxxxxxx> Subject: fanotify: reorganize loop in fanotify_read() Swap the error / "read ok" branches in the main loop of fanotify_read(). We will grow the "read ok" part in the next patch and this makes the indentation easier. Also it is more common to have error conditions inside an 'if' instead of the fast path.
