Subject: f2fs: don't set GC_FAILURE_PIN for background GC
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=642c0969916eaa4878cb74f36752108e590b0389;p=linux.git

f2fs: don't set GC_FAILURE_PIN for background GC

So that it can reduce the possibility that file be unpinned forcely by
foreground GC due to .i_gc_failures[GC_FAILURE_PIN] exceeds threshold.
