Subject: mm: compaction: show gfp flag names in try_to_compact_pages tracepoint
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b1746b991d621e35151386224f455fd6c0d291f0;p=openwrt%2Fstaging%2Fblogic.git

mm: compaction: show gfp flag names in try_to_compact_pages tracepoint

Showing the gfp flag names instead of the gfp_mask makes trace more
convenient.
