exofs: Add SYSFS info for autologin/pNFS export
Introduce sysfs infrastructure for exofs cluster filesystem. Each OSD target shows up as below in the sysfs hierarchy: /sys/fs/exofs/<osdname>_<partition_id>/devX Where <osdname>_<partition_id> is the unique identification of a Superblock. Where devX: 0 <= X < device_table_size. They are ordered in device-table order as specified to the mkfs.exofs command Each OSD device devX has following attributes : osdname - ReadOnly systemid - ReadOnly uri - Read/Write It is up to user-mode to update devX/uri for support of autologin. These sysfs information are used both for autologin as well as support for exporting exofs via a pNFSD server in user-mode.
