From 148817ba092f9f6edd35bad3c6c6b8e8f90fe2ed Mon Sep 17 00:00:00 2001 From: Akinobu Mita Date: Tue, 26 Jul 2011 16:09:04 -0700 Subject: asm-generic: add another generic ext2 atomic bitops The majority of architectures implement ext2 atomic bitops as test_and_{set,clear}_bit() without spinlock. This adds this type of generic implementation in ext2-atomic-setbit.h and use it wherever possible.
