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/ocfs2/dlmglue.c | 2 +- fs/ocfs2/file.c | 4 ++-- fs/ocfs2/file.h | 4 ++-- 3 files changed, 5 insertions(+), 5 deletions(-) (limited to 'fs/ocfs2') diff --git a/fs/ocfs2/dlmglue.c b/fs/ocfs2/dlmglue.c index 84f153aca692..64cd52860c87 100644 --- a/fs/ocfs2/dlmglue.c +++ b/fs/ocfs2/dlmglue.c @@ -2017,7 +2017,7 @@ out: return ret; } -static struct file_operations ocfs2_dlm_debug_fops = { +static const struct file_operations ocfs2_dlm_debug_fops = { .open = ocfs2_dlm_debug_open, .release = ocfs2_dlm_debug_release, .read = seq_read, diff --git a/fs/ocfs2/file.c b/fs/ocfs2/file.c index 4b4cbadd5838..34e903a6a46b 100644 --- a/fs/ocfs2/file.c +++ b/fs/ocfs2/file.c @@ -1176,7 +1176,7 @@ struct inode_operations ocfs2_special_file_iops = { .getattr = ocfs2_getattr, }; -struct file_operations ocfs2_fops = { +const struct file_operations ocfs2_fops = { .read = do_sync_read, .write = do_sync_write, .sendfile = generic_file_sendfile, @@ -1188,7 +1188,7 @@ struct file_operations ocfs2_fops = { .aio_write = ocfs2_file_aio_write, }; -struct file_operations ocfs2_dops = { +const struct file_operations ocfs2_dops = { .read = generic_read_dir, .readdir = ocfs2_readdir, .fsync = ocfs2_sync_file, diff --git a/fs/ocfs2/file.h b/fs/ocfs2/file.h index a5ea33b24060..740c9e7ca599 100644 --- a/fs/ocfs2/file.h +++ b/fs/ocfs2/file.h @@ -26,8 +26,8 @@ #ifndef OCFS2_FILE_H #define OCFS2_FILE_H -extern struct file_operations ocfs2_fops; -extern struct file_operations ocfs2_dops; +extern const struct file_operations ocfs2_fops; +extern const struct file_operations ocfs2_dops; extern struct inode_operations ocfs2_file_iops; extern struct inode_operations ocfs2_special_file_iops; struct ocfs2_alloc_context; -- cgit v1.2.3
