linux-toradex.git/include/linux/fs_stack.h, branch v2.6.39-rc7 Linux kernel for Apalis and Colibri modules VFS/fsstack: handle 32-bit smp + preempt + large files in fsstack_copy_inode_size 2009-12-17T15:58:17+00:00 Erez Zadok ezk@cs.sunysb.edu 2009-12-04T02:56:09+00:00 1b8ab8159ef8f818f870a1d2e3b6953d80eefd3f 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.

[PATCH] fsstack: Introduce fsstack_copy_{attr,inode}_* 2006-12-08T16:28:40+00:00 Josef "Jeff" Sipek jsipek@cs.sunysb.edu 2006-12-08T10:36:31+00:00 42cf11939becc717bd125d121a1a23415106a099 Introduce several fsstack_copy_* functions which allow stackable filesystems (such as eCryptfs and Unionfs) to easily copy over (currently only) inode attributes. This prevents code duplication and allows for code reuse.
