#     
#     Pull keyrings fixes from David Howells:
#      "Here's a couple of patches that fix a circular dependency between
#       holding key->sem and mm->mmap_sem when reading data from a key.
#     
#       One potential issue is that a filesystem looking to use a key inside,
#       say, ->readpages() could deadlock if the key being read is the key
#       that's required and the buffer the key is being read into is on a page
#       that needs to be fetched.
#     
#       The case actually detected is a bit more involved - with a filesystem
#       calling request_key() and locking the target keyring for write - which
#       could be being read"
