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

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?
