Subject: f2fs: drop FI_UPDATE_WRITE tag after f2fs_issue_flush
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3f06252f7aa5862591ee37fab63c4e95803880b6;p=openwrt%2Fstaging%2Fblogic.git

f2fs: drop FI_UPDATE_WRITE tag after f2fs_issue_flush

If we failed to issue flush in ->fsync, we need to keep FI_UPDATE_WRITE
flag to make sure triggering flush in next ->fsync.
