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/udf/dir.c | 2 +- fs/udf/file.c | 2 +- fs/udf/udfdecl.h | 4 ++-- 3 files changed, 4 insertions(+), 4 deletions(-) (limited to 'fs/udf') diff --git a/fs/udf/dir.c b/fs/udf/dir.c index f5222527fe3..8c28efa3b8f 100644 --- a/fs/udf/dir.c +++ b/fs/udf/dir.c @@ -42,7 +42,7 @@ static int do_udf_readdir(struct inode *, struct file *, filldir_t, void *); /* readdir and lookup functions */ -struct file_operations udf_dir_operations = { +const struct file_operations udf_dir_operations = { .read = generic_read_dir, .readdir = udf_readdir, .ioctl = udf_ioctl, diff --git a/fs/udf/file.c b/fs/udf/file.c index a6f2acc1f15..e34b00e303f 100644 --- a/fs/udf/file.c +++ b/fs/udf/file.c @@ -248,7 +248,7 @@ static int udf_release_file(struct inode * inode, struct file * filp) return 0; } -struct file_operations udf_file_operations = { +const struct file_operations udf_file_operations = { .read = generic_file_read, .ioctl = udf_ioctl, .open = generic_file_open, diff --git a/fs/udf/udfdecl.h b/fs/udf/udfdecl.h index 1d5800e0cbe..023e19ba5a2 100644 --- a/fs/udf/udfdecl.h +++ b/fs/udf/udfdecl.h @@ -44,9 +44,9 @@ struct buffer_head; struct super_block; extern struct inode_operations udf_dir_inode_operations; -extern struct file_operations udf_dir_operations; +extern const struct file_operations udf_dir_operations; extern struct inode_operations udf_file_inode_operations; -extern struct file_operations udf_file_operations; +extern const struct file_operations udf_file_operations; extern struct address_space_operations udf_aops; extern struct address_space_operations udf_adinicb_aops; extern struct address_space_operations udf_symlink_aops; -- cgit
