Subject: xfs: inode allocation should use unmapped buffers.
X-Git-Tag: v3.8-rc1~149^2~4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7c4cebe8e02dd0b0e655605442bbe9268db9ed4f;p=platform%2Fkernel%2Flinux-exynos.git

xfs: inode allocation should use unmapped buffers.

Inode buffers do not need to be mapped as inodes are read or written
directly from/to the pages underlying the buffer. This fixes a
regression introduced by commit 611c994 ("xfs: make XBF_MAPPED the
default behaviour").
