Description

Hey,

I just experienced the infamous ``cache_lock: blocked on 0xd591d418 ""'' message. Checking why the process got stuck revealed that the lock is actually being held by another process which is in the process of doing a lstat(2) on /mnt, a nfs mount which server went away. The stuck process is doing the same, fwiw.

So here it is not a namecache bug, but rather an artifact of nfs being stuck. Anoying nevertheless. Anybody have a clue how to fix that? Yea, mount with -intr. Why don't we do that per default?

cheers
simon
