From f6e58f01e8dc869803b9f73b2aa9d5bc3f32ca05 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Tue, 7 Nov 2006 15:14:58 -0500 Subject: [GFS2] Don't copy meta_header for rgrp in and out The meta_header for an ondisk rgrp never changes, so there is no point copying it in and back out to disk. Also there is no reason to keep a copy for each rgrp in memory. The code already checks to ensure that the header is correct before it calls the routine to copy the data in, so that we don't even need to check whether its correct on disk in the functions in ondisk.c Signed-off-by: Steven Whitehouse --- fs/gfs2/ondisk.c | 11 ----------- 1 file changed, 11 deletions(-) (limited to 'fs') diff --git a/fs/gfs2/ondisk.c b/fs/gfs2/ondisk.c index b2baba5c50b7..f2495f1e21ad 100644 --- a/fs/gfs2/ondisk.c +++ b/fs/gfs2/ondisk.c @@ -65,15 +65,6 @@ static void gfs2_meta_header_in(struct gfs2_meta_header_host *mh, const void *bu mh->mh_format = be32_to_cpu(str->mh_format); } -static void gfs2_meta_header_out(const struct gfs2_meta_header_host *mh, void *buf) -{ - struct gfs2_meta_header *str = buf; - - str->mh_magic = cpu_to_be32(mh->mh_magic); - str->mh_type = cpu_to_be32(mh->mh_type); - str->mh_format = cpu_to_be32(mh->mh_format); -} - void gfs2_sb_in(struct gfs2_sb_host *sb, const void *buf) { const struct gfs2_sb *str = buf; @@ -119,7 +110,6 @@ void gfs2_rgrp_in(struct gfs2_rgrp_host *rg, const void *buf) { const struct gfs2_rgrp *str = buf; - gfs2_meta_header_in(&rg->rg_header, buf); rg->rg_flags = be32_to_cpu(str->rg_flags); rg->rg_free = be32_to_cpu(str->rg_free); rg->rg_dinodes = be32_to_cpu(str->rg_dinodes); @@ -130,7 +120,6 @@ void gfs2_rgrp_out(const struct gfs2_rgrp_host *rg, void *buf) { struct gfs2_rgrp *str = buf; - gfs2_meta_header_out(&rg->rg_header, buf); str->rg_flags = cpu_to_be32(rg->rg_flags); str->rg_free = cpu_to_be32(rg->rg_free); str->rg_dinodes = cpu_to_be32(rg->rg_dinodes); -- cgit v1.2.2
