[PATCH v2 04/12] mempolicy trivia: delete those ancient pr_debug()s

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Delete those ancient pr_debug()s - PDprintk()s in Andi Kleen's original
submission of core NUMA API, and useful when debugging shared mempolicy
lifetime back then, but not used recently.
