|
;Abstract:
|
|
|
|
; All global spinlocks in the kernel image are declared in this
|
|
; module. This is done so that each spinlock can be spaced out
|
|
; sufficiently to guaarantee that the L2 cache does not thrash
|
|
; by having a spinlock and another high use variable in the same
|
|
; cache line.
