-Subject: [PATCH hurd 2/2] ext2fs: fix pager use-after-free
-
-Previously, pagers had no reference for being part of a node, only for
-having a send right made for them.  Hence we sometimes saw
-use-after-free errors if the kernel did give up that send right,
-typically while deleting files.  Keep a weak reference as long as the
-pager is referenced by a node.
-
-* ext2fs/pager.c (pager_clear_user_data): Assert that 'pager' has been
-NULLed.
-(pager_dropweak): Drop the weak reference and NULL 'pager'.
-(diskfs_get_filemap): Simplify.  Acquire a weak reference.
