I don't think it makes sense to fix this in any way though. If cmpxchg does not work, then there are bound to be bigger problems than just atomically decrementing/incrementing nr_readers and the real fix is to fix/change the hardware. Frank, please go ahead and post your patch anyway, so that we know what the glibc community consensus is on this. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
