Alexander Motin 5f6a3a81f6 GEOM: Introduce partial confxml API ... Traditionally the GEOM's primary channel of information from kernel to user-space was confxml, fetched by libgeom through kern.geom.confxml sysctl. It is convenient and informative, representing full state of GEOM in a single XML document. But problems start to arise on systems with hundreds of disks, where the full confxml size reaches many megabytes, taking significant time to first write it and then parse. This patch introduces alternative solution, allowing to fetch much smaller XML document, subset of the full confxml, limited to 64KB and representing only one specified geom and optionally its parents. It uses existing GEOM control interface, extended with new "getxml" verb. In case of any error, such as the buffer overflow, it just transparently falls back to traditional full confxml. This patch uses the new API in user-space GEOM tools where it is possible. Reviewed by: imp MFC after: 2 month Sponsored by: iXsystems, Inc.
