Before I wrote code that's not useful at all: I don't quite get why
retry on buffer overflow is necessary at all. It looks like it once
seemed to be a useful kludge, but then 1b71fe2efa31 ("ceph analog of
cifs build_path_from_dentry() race fix") added the read_seqretry()
check which, to my limited understanding, is a more robust
implementation of rename detection.
