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/9p/v9fs_vfs.h | 4 ++-- fs/9p/vfs_dir.c | 2 +- fs/9p/vfs_file.c | 2 +- 3 files changed, 4 insertions(+), 4 deletions(-) (limited to 'fs/9p') diff --git a/fs/9p/v9fs_vfs.h b/fs/9p/v9fs_vfs.h index 43c9f7de031..f867b8d3e97 100644 --- a/fs/9p/v9fs_vfs.h +++ b/fs/9p/v9fs_vfs.h @@ -39,8 +39,8 @@ extern struct file_system_type v9fs_fs_type; extern struct address_space_operations v9fs_addr_operations; -extern struct file_operations v9fs_file_operations; -extern struct file_operations v9fs_dir_operations; +extern const struct file_operations v9fs_file_operations; +extern const struct file_operations v9fs_dir_operations; extern struct dentry_operations v9fs_dentry_operations; struct inode *v9fs_get_inode(struct super_block *sb, int mode); diff --git a/fs/9p/vfs_dir.c b/fs/9p/vfs_dir.c index 766f11f1215..e32d5971039 100644 --- a/fs/9p/vfs_dir.c +++ b/fs/9p/vfs_dir.c @@ -204,7 +204,7 @@ int v9fs_dir_release(struct inode *inode, struct file *filp) return 0; } -struct file_operations v9fs_dir_operations = { +const struct file_operations v9fs_dir_operations = { .read = generic_read_dir, .readdir = v9fs_dir_readdir, .open = v9fs_file_open, diff --git a/fs/9p/vfs_file.c b/fs/9p/vfs_file.c index 59e74416340..083dcfcd158 100644 --- a/fs/9p/vfs_file.c +++ b/fs/9p/vfs_file.c @@ -266,7 +266,7 @@ v9fs_file_write(struct file *filp, const char __user * data, return total; } -struct file_operations v9fs_file_operations = { +const struct file_operations v9fs_file_operations = { .llseek = generic_file_llseek, .read = v9fs_file_read, .write = v9fs_file_write, -- cgit v1.2.3
