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/coda/dir.c | 2 +- fs/coda/file.c | 2 +- fs/coda/pioctl.c | 2 +- fs/coda/psdev.c | 2 +- 4 files changed, 4 insertions(+), 4 deletions(-) (limited to 'fs/coda') diff --git a/fs/coda/dir.c b/fs/coda/dir.c index 54f76de8a686..71f2ea632e53 100644 --- a/fs/coda/dir.c +++ b/fs/coda/dir.c @@ -82,7 +82,7 @@ struct inode_operations coda_dir_inode_operations = .setattr = coda_setattr, }; -struct file_operations coda_dir_operations = { +const struct file_operations coda_dir_operations = { .llseek = generic_file_llseek, .read = generic_read_dir, .readdir = coda_readdir, diff --git a/fs/coda/file.c b/fs/coda/file.c index 146a991d6eb5..7c2642431fa5 100644 --- a/fs/coda/file.c +++ b/fs/coda/file.c @@ -288,7 +288,7 @@ int coda_fsync(struct file *coda_file, struct dentry *coda_dentry, int datasync) return err; } -struct file_operations coda_file_operations = { +const struct file_operations coda_file_operations = { .llseek = generic_file_llseek, .read = coda_file_read, .write = coda_file_write, diff --git a/fs/coda/pioctl.c b/fs/coda/pioctl.c index 127714936c66..214822be87bd 100644 --- a/fs/coda/pioctl.c +++ b/fs/coda/pioctl.c @@ -36,7 +36,7 @@ struct inode_operations coda_ioctl_inode_operations = .setattr = coda_setattr, }; -struct file_operations coda_ioctl_operations = { +const struct file_operations coda_ioctl_operations = { .owner = THIS_MODULE, .ioctl = coda_pioctl, }; diff --git a/fs/coda/psdev.c b/fs/coda/psdev.c index 98c74fe2e139..6c6771db36da 100644 --- a/fs/coda/psdev.c +++ b/fs/coda/psdev.c @@ -342,7 +342,7 @@ static int coda_psdev_release(struct inode * inode, struct file * file) } -static struct file_operations coda_psdev_fops = { +static const struct file_operations coda_psdev_fops = { .owner = THIS_MODULE, .read = coda_psdev_read, .write = coda_psdev_write, -- cgit v1.2.3-59-g8ed1b
