From 1b8ab8159ef8f818f870a1d2e3b6953d80eefd3f Mon Sep 17 00:00:00 2001 From: Erez Zadok Date: Thu, 3 Dec 2009 21:56:09 -0500 Subject: VFS/fsstack: handle 32-bit smp + preempt + large files in fsstack_copy_inode_size Copy the inode size and blocks from one inode to another correctly on 32-bit systems with CONFIG_SMP, CONFIG_PREEMPT, or CONFIG_LBDAF. Use proper inode spinlocks only when i_size/i_blocks cannot fit in one 32-bit word.
