From: Ryan Haasken Date: Sun, 27 Apr 2014 17:07:01 +0000 (-0400) Subject: staging/lustre/llite: Do not rate limit dirty page discard warning X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=73b8990780e3aa0a31326fb1ae338646620176d1;p=openwrt%2Fstaging%2Fblogic.git staging/lustre/llite: Do not rate limit dirty page discard warning Messages which are printed by ll_dirty_page_discard_warn() should not be rate limited. If they are rate limited, some files which may be corrupted on client eviction will not be reported to the user. This patch changes the CWARN to a CDEBUG to disable console message rate limiting for this message. The dirty page discard warnings are already limited on a per-file basis by the function vvp_vmpage_error which calls ll_dirty_page_discard_warn only if the ccc_object's cob_discard_page_warned == 0.
