Subject: mm/hugetlb: GFP_KERNEL allocation under spinlock?
Date: Sun, 02 Aug 2009 10:44:49 +0200 [thread overview]
Message-ID: <4A755201.1010200@gmail.com> (raw)
Hi,
could anybody please confirm this cannot happen?
hugetlb_fault()
-> spin_lock()
-> hugetlb_cow()
-> alloc_huge_page()
-> vma_needs_reservation()
-> region_chg() (either of the 2)
-> kmalloc(*, GFP_KERNEL)
Thanks.
