Andrew, let me know if I've misunderstood how you want to see it. Here's the commit for the NFS people to chew on a bit. commit f05b88f294044cdf56fbe637a246ba6c7a14d6f1 Author: Matthew Wilcox <matthew@xxxxxx> Date: Thu Dec 6 16:24:39 2007 -0500 NFS: Switch from intr mount option to TASK_KILLABLE By using the TASK_KILLABLE infrastructure, we can get rid of the 'intr' mount option. We have to use _killable everywhere instead of _interruptible as we get rid of rpc_clnt_sigmask/sigunmask. Signed-off-by: Liam R.
