Date: Thu, 25 Jul 2013 18:58:54 -0400 From: Johannes Weiner <hannes@...xchg.org> To: Andrew Morton <akpm@...ux-foundation.org> Cc: Paul Szabo <psz@...hs.usyd.edu.au>, Rik van Riel <riel@...hat.com>, linux-mm@...ck.org, linux-kernel@...r.kernel.org Subject: [patch] Revert "page-writeback.c: subtract min_free_kbytes from dirtyable memory" This reverts commit 75f7ad8e043d9383337d917584297f7737154bbf. It was the result of a problem observed with a 3.2 kernel and merged in 3.9, while the issue had been resolved upstream in 3.3 (ab8fabd mm: exclude reserved pages from dirtyable memory). The "reserved pages" are a superset of min_free_kbytes, thus this change is redundant and confusing. Revert it.
