[PATCH 0/5] vfs: track the dentry name length in name_snapshot

[Jeff Layton]

name_snapshot will snapshot the current contents of a dentry's name for
later consumption. Several of those users end up needing to do a strlen
on the resulting string later. We already have that info in the original
dentry though, so we can do this a bit more efficiently by stuffing the
name length into the name_snapshot as well.

This is not well tested, but it built and booted. Do we have a testsuite
that exercises the fsnotify code, in particular?

Jeff Layton (5):
  dcache: track the length of the string in struct name_snapshot
  fsnotify: have fsnotify_move take a struct qstr instead of a string
  fsnotify: have fsnotify() take a qstr instead of a string
  fsnotify: change ->handle_event and send_to_group to take a qstr
  audit: fix audit_compare_dname_path to take a qstr
