Subject: [PATCH]: Better handling of PG_dcache_dirty
Date: Thu, 27 Mar 2003 03:54:34 +0100 [thread overview]
Message-ID: <m2znnhcydx.fsf@mandrakesoft.com> (raw)
Hi
Use coherent names:
s/Page_dcache_dirty/PageDcacheDirty/
And remove WO pg_flags variable (too much copy & paste from sparc64).
Later, Juan.
