Subject: [PATCH 26/35] staging: lustre: mdc: remove console spew from mdc_ioc_fid2path
Date: Thu, 10 Nov 2016 12:30:56 -0500 [thread overview]
Message-ID: <1478799065-24841-27-git-send-email-jsimmons@infradead.org> (raw)
In-Reply-To: <1478799065-24841-1-git-send-email-jsimmons@infradead.org>
From: Andreas Dilger <andreas.dilger@intel.com>
In some cases with a very long pathname, such as with sanity.sh
test_154c, mdc_ioc_fid2path() would spew long debug messages to
the log, because libcfs_debug_vmsg2() refuses to log messages over
one page in size.
Truncate the debug message to only log the last 512 characters
of the pathname, which is sufficient for most debugging, saves a
bit of space in the debug log, and will prevent the debug logging
from printing to the console in the first place.
