Previously, we can't map same device name from different sessions due to the limitation of sysfs naming mechanism. root@clt2:~# ls -l /sys/class/rnbd-client/ctl/devices/ total 0 lrwxrwxrwx 1 root 0 Sep 2 16:31 !dev!nullb1 -> ../../../block/rnbd0 We only use the device name in above, which caused device with the same name can't be mapped from another server. To address the issue, the sessname is appended to the node to differentiate where the device comes from. Also, we need to check if the pathname is existed in a specific session instead of search it in global sess_list.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
