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/reiserfs/dir.c | 2 +- fs/reiserfs/file.c | 2 +- fs/reiserfs/procfs.c | 2 +- 3 files changed, 3 insertions(+), 3 deletions(-) (limited to 'fs/reiserfs') diff --git a/fs/reiserfs/dir.c b/fs/reiserfs/dir.c index d71ac6579289..973c819f8033 100644 --- a/fs/reiserfs/dir.c +++ b/fs/reiserfs/dir.c @@ -18,7 +18,7 @@ static int reiserfs_readdir(struct file *, void *, filldir_t); static int reiserfs_dir_fsync(struct file *filp, struct dentry *dentry, int datasync); -struct file_operations reiserfs_dir_operations = { +const struct file_operations reiserfs_dir_operations = { .read = generic_read_dir, .readdir = reiserfs_readdir, .fsync = reiserfs_dir_fsync, diff --git a/fs/reiserfs/file.c b/fs/reiserfs/file.c index d0c1e865963e..010094d14da6 100644 --- a/fs/reiserfs/file.c +++ b/fs/reiserfs/file.c @@ -1566,7 +1566,7 @@ static ssize_t reiserfs_aio_write(struct kiocb *iocb, const char __user * buf, return generic_file_aio_write(iocb, buf, count, pos); } -struct file_operations reiserfs_file_operations = { +const struct file_operations reiserfs_file_operations = { .read = generic_file_read, .write = reiserfs_file_write, .ioctl = reiserfs_ioctl, diff --git a/fs/reiserfs/procfs.c b/fs/reiserfs/procfs.c index ef6caed9336b..731688e1cfe3 100644 --- a/fs/reiserfs/procfs.c +++ b/fs/reiserfs/procfs.c @@ -470,7 +470,7 @@ static int r_open(struct inode *inode, struct file *file) return ret; } -static struct file_operations r_file_operations = { +static const struct file_operations r_file_operations = { .open = r_open, .read = seq_read, .llseek = seq_lseek, -- cgit v1.2.2
