Subject: RE: [PATCH v2] pstore: Adjust buffer size for compression for
 smaller registered buffers

+	default:

Is this the right "default"?  It may be a good choice for a backend with a really
tiny buffer (1 ... 999).  But less good for a (theoretical) backend with a larger
buffer (10001 ... infinity and beyond).  Which are you trying to catch here?
