Revision 9ab4233dd08036fe34a89c7dc6f47a8bf2eb29eb authored by Andy Lutomirski on 05 July 2012, 23:00:11 UTC, committed by Linus Torvalds on 06 July 2012, 17:34:38 UTC
Otherwise the code races with munmap (causing a use-after-free
of the vma) or with close (causing a use-after-free of the struct
file).
The bug was introduced by commit 90ed52ebe481 ("[PATCH] holepunch: fix
mmap_sem i_mutex deadlock")
