Subject: [PATCH mask 8/15] mask2-bitmap-extensions
Date: Thu, 6 May 2004 11:48:46 -0700 [thread overview]
Message-ID: <20040506114846.76640bae.pj@sgi.com> (raw)
In-Reply-To: <20040506111814.62d1f537.pj@sgi.com>
mask2-bitmap-extensions
This bitmap improvements make it a suitable basis for
fully supporting cpumask_t and nodemask_t. Inline macros
with compile-time checks enable generating tight code on
both small and large systems (large meaning cpumask_t
requires more than one unsigned long's worth of bits).
The existing bitmap_<op> macros in lib/bitmap.c
are renamed to __bitmap_<op>, and wrappers for each
bitmap_<op> are exposed in include/linux/bitmap.h
This patch _includes_ Bill Irwins rewrite of the
bitmap_shift operators to not require a fixed length
intermediate bitmap.
Improved comments list each available operator for easy
browsing.
