#      "This cycle addresses a reported permission issue with overlay due to a
#       duplicated permission check for "trusted." xattrs. Also, a REQ_RAHEAD
#       flag is added now to all readahead requests in order to trace
#       readahead I/Os. The others are random cleanups.
#     
#       All commits have been tested and have been in linux-next as well.
#
