[Xen-devel] [PATCH v2 0/5] Allow runtime adjustment to log level thresholds

[Wei Liu <wei.liu2@xxxxxxxxxx>]

Previously Jan posted [0]. The downside of that approach is that we need to
rework log level number space to make it suitable for stable API (safe against
addition and removal of numbers).

This version changes the interface to use buffers that contain string
representation of log level. User space libraries won't care about what is
inside. The parsing and interpretation is up to the hypervisor.

Wei.
