From fd88de569b802c4a04aaa6ee74667775f4aed8c6 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Fri, 5 May 2006 16:59:11 -0400 Subject: [GFS2] Readpages support This adds readpages support (and also corrects a small bug in the readpage error path at the same time). Hopefully this will improve performance by allowing GFS to submit larger lumps of I/O at a time. In order to simplify the setting of BH_Boundary, it currently gets set when we hit the end of a indirect pointer block. There is always a boundary at this point with the current allocation code. It doesn't get all the boundaries right though, so there is still room for improvement in this. See comments in fs/gfs2/ops_address.c for further information about readpages with GFS2.
