Subject: [lustre-devel] [PATCH 30/41] lustre: lov: style cleanups in lov_set_osc_active()
Date: Sun,  4 Apr 2021 20:50:59 -0400	[thread overview]
Message-ID: <1617583870-32029-31-git-send-email-jsimmons@infradead.org> (raw)
In-Reply-To: <1617583870-32029-1-git-send-email-jsimmons@infradead.org>

From: Mr NeilBrown <neilb@suse.de>

1/ don't pre-declare the function as it is not used before it
   is defined.
2/ " TEST ? 1 : 0" is identical to "TEST", so remove the "? 1 : 0".
3/ When the 'then' part of an 'if' ends with a goto, there is
   not point having an 'else', particularly if there is also
   code in the block following the "if".  The 'else' code and
   the following code should be together.

4/ other minor changes, and conversion of spaces to tabs.

WC-bug-id: https://jira.whamcloud.com/browse/LU-6142
