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/autofs/autofs_i.h | 2 +- fs/autofs/root.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) (limited to 'fs/autofs') diff --git a/fs/autofs/autofs_i.h b/fs/autofs/autofs_i.h index 990c28da5ae..a62327f1bdf 100644 --- a/fs/autofs/autofs_i.h +++ b/fs/autofs/autofs_i.h @@ -146,7 +146,7 @@ struct autofs_dir_ent *autofs_expire(struct super_block *,struct autofs_sb_info extern struct inode_operations autofs_root_inode_operations; extern struct inode_operations autofs_symlink_inode_operations; -extern struct file_operations autofs_root_operations; +extern const struct file_operations autofs_root_operations; /* Initializing function */ diff --git a/fs/autofs/root.c b/fs/autofs/root.c index 870e2cf3301..9cac08d6a87 100644 --- a/fs/autofs/root.c +++ b/fs/autofs/root.c @@ -26,7 +26,7 @@ static int autofs_root_rmdir(struct inode *,struct dentry *); static int autofs_root_mkdir(struct inode *,struct dentry *,int); static int autofs_root_ioctl(struct inode *, struct file *,unsigned int,unsigned long); -struct file_operations autofs_root_operations = { +const struct file_operations autofs_root_operations = { .read = generic_read_dir, .readdir = autofs_root_readdir, .ioctl = autofs_root_ioctl, -- cgit v1.2.3-70-g09d2
