Subject: fs: dcache fix LRU ordering
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c490d79bb70c549e096099576b1df40a8810b0d8;p=linux.git

fs: dcache fix LRU ordering

Fix ordering of LRU when moving referenced dentries to the head of the list
(they should go to the head of the list in the same order as they were found
from the tail, rather than reverse order).
