Subject: [3.0-rc1] delayed insertion allocation failing...
Date: Mon, 30 May 2011 22:24:08 +0800 [thread overview]
Message-ID: <BANLkTinv0GDkGy6mhC2DVrt6wW7ZGQPPrQ@mail.gmail.com> (raw)
Hi Miao,
When booting 3.0-rc1 with an existing BTRFS filesystem with a normal
desktop use pattern, we see btrfs_batch_insert_item() sometimes
attempt an overly-large kmalloc (>= order 11) [1], which is
subsequently failed.
Thanks,
Daniel
