Subject: f2fs: don't drop any page on f2fs_cp_error() case
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=868de6135f060b966a9320cc54bf12249b5c0f99;p=linux.git

f2fs: don't drop any page on f2fs_cp_error() case

We still provide readdir() after shtudown, so we should keep pages to avoid
additional IOs.
