The patch titled fs: inode.c use atomic_inc_return in __iget has been removed from the -mm tree. Its filename was fs-inodec-use-atomic_inc_return-in-__iget.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: fs: inode.c use atomic_inc_return in __iget From: Richard Kennedy <richard@xxxxxxxxxxxxxxx> Using atomic_inc_return in __iget(struct inode *inode) makes the intent of this code clearer and generates less code on processors that have this operation. On x86_64 this patch reduces the text size of inode.o by 12 bytes.
