It also\naccounted/unaccounted the pages against the current->mm. But its possible\nthe unaccount_mem() can be called from a different process context than the\none that originally pinned the pages.\n\nLet's fix this by storing the pinning process user_struct and mm_struct\nwhen accounting for pinned pages, and subsequently free these resources\nwhen the pages are unpinned.\n\n[borntraeger@linux.ibm.com: Fixed whitespace]"
