Description

The RFS defaults to max_held_buffers or 5. On small cache sizes with a few RFS file system active this can use up the buffers in the cache causing a deadlock as the file system waits for a buffer. The RFS need a way to configure the number of buffers held and to be able to disable the RFS local caching.

The patch add support for "hold-bitmaps,no-local-cache,max-held-bufs=2".

The patch also contains a minor fix for the bdbuf state trace printing.
