Subject: [PATCH 3/3 v2] xfsprogs: allow linking against libtcmalloc
Date: Mon, 21 Nov 2011 06:59:25 -0500 [thread overview]
Message-ID: <20111121115925.GA12209@infradead.org> (raw)
In-Reply-To: <20111119184507.GA11208@infradead.org>
Allow linking against the libtcmalloc library from Google's performance
tools, which at least for repair reduces the memory usage dramatically.
Note that the current version of the autoconf-foo mostly comes from
Arek, mine was much inferior to it.
