"I've long hated the non-killability of tasks accessing a dead NFS server," Matthew Wilcox said along with a prototype patch to fix the issue based on a 2002 posting by Linus Torvalds. Matthew added, "I've only added one real user of the killable concept to this patch -- try_lock_page(). However, this is enough for 'cat */*/*' to be killable with a ^C when I unplug the ethernet cord between it and the nfs server."

Linus responded favorably to the patch, "hey, I obviously approve. And the patch looks simple." He went on to suggest that he was interested in merging the patch during the next merge window, "feel free to re-submit after 2.6.23 is out the door, I don't think anybody will really complain. Any NFS user will know why something like this can be really nice."
