Subject: [patch 12/12] mark struct inode_operations const 3
From: Arjan van de Ven <arjan@...ux.intel.com>
Subject: [patch 12/12] mark struct inode_operations const
Many struct inode_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.
