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/fifo.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'fs/fifo.c') diff --git a/fs/fifo.c b/fs/fifo.c index d13fcd3ec80..889f722ee36 100644 --- a/fs/fifo.c +++ b/fs/fifo.c @@ -145,6 +145,6 @@ err_nocleanup: * is contain the open that then fills in the correct operations * depending on the access mode of the file... */ -struct file_operations def_fifo_fops = { +const struct file_operations def_fifo_fops = { .open = fifo_open, /* will set read or write pipe_fops */ }; -- cgit v1.2.3
