Subject: [PATCH] mark struct file_operations const 7
X-Git-Tag: v2.6.21-rc1~274^2~10
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=9a32144e9d7b4e21341174b1a83b82a82353be86;p=linux-2.6-omap-h63xx.git

[PATCH] mark struct file_operations const 7

Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.
