From: Chuck Lever Date: Sat, 6 Dec 2008 00:03:54 +0000 (-0500) Subject: NLM: Call nsm_reboot_lookup() instead of nsm_find() X-Git-Tag: firefly_0821_release~16077^2~31 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=8c7378fd2a5f22016542931b887a2ae98d146eaf;p=firefly-linux-kernel-4.4.55.git NLM: Call nsm_reboot_lookup() instead of nsm_find() Invoke the newly introduced nsm_reboot_lookup() function in nlm_host_rebooted() instead of nsm_find(). This introduces just one behavioral change: debugging messages produced during reboot notification will now appear when the NLMDBG_MONITOR flag is set, but not when the NLMDBG_HOSTCACHE flag is set.
