Subject: f2fs: fix to enable ATGC correctly via gc_idle sysfs interface
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d8c8dd97bb8cd5d1ab2857850e6166e51417435e;p=linux.git

f2fs: fix to enable ATGC correctly via gc_idle sysfs interface

[ Upstream commit 7d19e3dab0002e527052b0aaf986e8c32e5537bf ]

It needs to assign sbi->gc_mode with GC_IDLE_AT rather than GC_AT when
user tries to enable ATGC via gc_idle sysfs interface, fix it.
