Re: Source code of SMB2 Kernel module

[Shinnosuke Yagi <yagi.shinnosuke-o7dWnD6vFTHqq2nvvmkE/A@public.gmane.org>]

I patched and tried to mount again.

I mount successfully by smb2.
However, Kernel clashed when I accessed to mounted FS.

I couldn't got any logs, because I did not set kdump.

I will try to get a clashed kernel dump.

Please wait.


Thanks.
