[akpm]

The patch titled
     Subject: zram: cosmetic: cleanup documentation
has been removed from the -mm tree.  Its filename was
     zram-cosmetic-cleanup-documentation.patch

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

From: Sergey Senozhatsky <sergey.senozhatsky@gmail.com>
Subject: zram: cosmetic: cleanup documentation

zram documentation is a mix of different styles: spaces, tabs, tabs +
spaces, etc.  Clean it up.

-        Set disk size by writing the value to sysfs node 'disksize'.
