Tony Luck 01d69a82e1 [IA64] Fix 64-bit atomic routines to return "long" ... These have been broken (returning "int") since the dawn of time. But there were no users that needed the whole value until commit 424acaaeb3 rwsem: wake queued readers when writer blocks on active read lock made this change: - (rwsem_atomic_update(0, sem) & RWSEM_ACTIVE_MASK)) - /* Someone grabbed the sem already */ + rwsem_atomic_update(0, sem) < RWSEM_WAITING_BIAS) + /* Someone grabbed the sem for write already */ RWSEM_ACTIVE_MASK is 0xffffffffL, so the old code only looked at the low order 32-bits. The new code needs to see all 64 bits. Signed-off-by: Tony Luck <tony.luck@intel.com>		2010-08-13 16:41:07 -07:00
