Subject: [PATCH v2 06/18] IB/uverbs: pack struct ib_uverbs_event_file tighter
Date: Tue, 02 Feb 2010 12:08:14 -0700 [thread overview]
Message-ID: <20100202190814.28217.61115.stgit@bob.kio> (raw)
In-Reply-To: <20100202185235.28217.64521.stgit-tBlMHHroXgg@public.gmane.org>
Eliminate some padding in the structure by rearranging the members.
sizeof(struct ib_uverbs_event_file) is now 72 bytes (from 80) and
more members now fit in the first cacheline.
