Brian Behlendorf	3b6425cb5b	Fix atomic_sub_64() i386 assembly implementation ... The atomic_sub_64() should use sbbl instead of adcl. In user space these atomics are used for statistics tracking and aren't critical which explain how this was overlooked. The kernel space implementation of these atomics are layered on the architecture specific implementations provided by the kernel.

Etienne Dechamps	142e6dd100	Add atomic_sub_* functions to libspl. ... Both the SPL and the ZFS libspl export most of the atomic_* functions, except atomic_sub_* functions which are only exported by the SPL, not by libspl. This patch remedies that by implementing atomic_sub_* functions in libspl. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Issue #1013	2012-10-17 08:56:37 -07:00
