[patch 0/3 resend] mm: close race between dirtying and truncation

[Johannes Weiner]

Hi Andrew,

it looks like these 3 patches fell on the floor.  The first one is a
bug fix that closes a race condition between truncation and dirtying
from do_wp_page(), which can result in a dirty-accounting error.  #2
and #3 simplify the code in the area.  Please consider them for 3.19.

Thanks!
