Subject: [f2fs-dev] [PATCH 4/5] f2fs: check return value of f2fs_readpage in find_data_page
Date: Thu, 28 Nov 2013 15:43:43 +0800 [thread overview]
Message-ID: <003601ceec0d$bcc30330$36490990$@samsung.com> (raw)
We should return error if we do not get an updated page in find_date_page
when f2fs_readpage failed.
