From 4de0ae322cb45ae3620fef3a8fcf76d44208ee44 Mon Sep 17 00:00:00 2001 From: jeff Date: Tue, 4 Mar 2003 00:04:44 +0000 Subject: - Add a new 'flags' parameter to getblk(). - Define one flag GB_LOCK_NOWAIT that tells getblk() to pass the LK_NOWAIT flag to the initial BUF_LOCK(). This will eventually be used in cases were we want to use a buffer only if it is not currently in use. - Convert all consumers of the getblk() api to use this extra parameter.
