Subject: NFS: writepage of a single page should not be synchronous
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=811ed92ecc9f47eee90beabcf5c2133f2a6d2440;p=openwrt%2Fstaging%2Fblogic.git

NFS: writepage of a single page should not be synchronous

It is almost always better to wait for more so that we can issue a
bulk commit.
