David Chinner 01e1b69cfc [XFS] using a spinlock per cpu for superblock counter exclusion results in ... a preēmpt counter overflow at 256p and above. Change the exclusion mechanism to use atomic bit operations and busy wait loops to emulate the spin lock exclusion mechanism but without the preempt count issues.
