From: Jesper Juhl Date: Mon, 21 Mar 2011 19:47:31 +0000 (+0100) Subject: Reduce sequential pointer derefs in scsi_error.c and reduce size as well X-Git-Tag: v2.6.39-rc1~392 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0bf8c869701039b12c3520cb1bb1689595ab108b;p=pandora-kernel.git Reduce sequential pointer derefs in scsi_error.c and reduce size as well This patch reduces the number of sequential pointer derefs in drivers/scsi/scsi_error.c This has been submitted a number of times over a couple of years. I believe this version adresses all comments it has gathered over time. Please apply or reject with a reason. The benefits are: - makes the code easier to read. Lots of sequential derefs of the same pointers is not easy on the eye. - theoretically at least, just dereferencing the pointers once can allow the compiler to generally slightly faster code, so in theory this could also be a micro speed optimization. - reduces size of object file (tiny effect: on x86-64, in at least one configuration, the text size decreased from 9439 bytes to 9400) - removes some pointless (mostly trailing) whitespace.
