Chao Yu 250dbf5151 f2fs: fix to avoid race during access gc_thread pointer ... Thread A Thread B - f2fs_remount - stop_gc_thread - f2fs_sbi_store sbi->gc_thread = NULL; access sbi->gc_thread->gc_* Previously, we allocate memory for sbi->gc_thread based on background gc thread mount option, the memory can be released if we turn off that mount option, but still there are several places access gc_thread pointer without considering race condition, result in NULL point dereference. In order to fix this issue, use sb->s_umount to exclude those operations. Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>		2018-05-31 11:31:52 -07:00
