From 4b6f5d20b04dcbc3d888555522b90ba6d36c4106 Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Tue, 28 Mar 2006 01:56:42 -0800 Subject: [PATCH] Make most file operations structs in fs/ const This is a conversion to make the various file_operations structs in fs/ const. Basically a regexp job, with a few manual fixups The goal is both to increase correctness (harder to accidentally write to shared datastructures) and reducing the false sharing of cachelines with things that get dirty in .data (while .rodata is nicely read only and thus cache clean) Signed-off-by: Arjan van de Ven Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- fs/afs/internal.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'fs/afs/internal.h') diff --git a/fs/afs/internal.h b/fs/afs/internal.h index ab8f87c6631..72febdf9a35 100644 --- a/fs/afs/internal.h +++ b/fs/afs/internal.h @@ -64,7 +64,7 @@ extern struct cachefs_index_def afs_cache_cell_index_def; * dir.c */ extern struct inode_operations afs_dir_inode_operations; -extern struct file_operations afs_dir_file_operations; +extern const struct file_operations afs_dir_file_operations; /* * file.c @@ -105,7 +105,7 @@ extern struct cachefs_netfs afs_cache_netfs; * mntpt.c */ extern struct inode_operations afs_mntpt_inode_operations; -extern struct file_operations afs_mntpt_file_operations; +extern const struct file_operations afs_mntpt_file_operations; extern struct afs_timer afs_mntpt_expiry_timer; extern struct afs_timer_ops afs_mntpt_expiry_timer_ops; extern unsigned long afs_mntpt_expiry_timeout; -- cgit v1.2.3
