Subject: [PATCH] dnotify fix for readv/writev (Linux 2.4.20)
Date: Mon, 2 Dec 2002 09:22:43 +0800	[thread overview]
Message-ID: <200212020922.43820.pczou@redflag-linux.com> (raw)

hi, Marcelo,

this is a patch to fix the dnotify bug of readv/writev. 

Orignally DN_MODIFY is issued on readv while DN_ACCESS is issued on writev, 
which is obviously wrong. This patch fixes such problem.

cheers,
