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/ramfs/file-mmu.c | 2 +- fs/ramfs/file-nommu.c | 2 +- fs/ramfs/internal.h | 2 +- 3 files changed, 3 insertions(+), 3 deletions(-) (limited to 'fs/ramfs') diff --git a/fs/ramfs/file-mmu.c b/fs/ramfs/file-mmu.c index 6ada209..00a933e 100644 --- a/fs/ramfs/file-mmu.c +++ b/fs/ramfs/file-mmu.c @@ -32,7 +32,7 @@ struct address_space_operations ramfs_aops = { .commit_write = simple_commit_write }; -struct file_operations ramfs_file_operations = { +const struct file_operations ramfs_file_operations = { .read = generic_file_read, .write = generic_file_write, .mmap = generic_file_mmap, diff --git a/fs/ramfs/file-nommu.c b/fs/ramfs/file-nommu.c index b1ca234..f443a84 100644 --- a/fs/ramfs/file-nommu.c +++ b/fs/ramfs/file-nommu.c @@ -33,7 +33,7 @@ struct address_space_operations ramfs_aops = { .commit_write = simple_commit_write }; -struct file_operations ramfs_file_operations = { +const struct file_operations ramfs_file_operations = { .mmap = ramfs_nommu_mmap, .get_unmapped_area = ramfs_nommu_get_unmapped_area, .read = generic_file_read, diff --git a/fs/ramfs/internal.h b/fs/ramfs/internal.h index 272c8a7..3132376 100644 --- a/fs/ramfs/internal.h +++ b/fs/ramfs/internal.h @@ -11,5 +11,5 @@ extern struct address_space_operations ramfs_aops; -extern struct file_operations ramfs_file_operations; +extern const struct file_operations ramfs_file_operations; extern struct inode_operations ramfs_file_inode_operations; -- cgit v1.1
