From c2932e03dbcfe7ea9052953dbd5f3157183c1e9b Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Thu, 1 Nov 2007 09:26:54 +0000 Subject: [PATCH] [GFS2] Remove "reclaim limit" This call to reclaim glocks is not needed, and in particular we don't want it in the fast path for locking glocks. The limit was entirely arbitrary anyway and we can't expect users to adjust things like this, the remaining code will do the right thing on its own.
