Subject: [PATCH 1/2] f2fs: add F2FS_GOING_DOWN_METAFLUSH to test power-failure
Date: Thu, 8 Oct 2015 17:29:25 -0700 [thread overview]
Message-ID: <1444350566-37795-1-git-send-email-jaegeuk@kernel.org> (raw)
This patch introduces F2FS_GOING_DOWN_METAFLUSH which flushes meta pages like
SSA blocks and then blocks all the writes.
This can be used by power-failure tests.
