Re: [PATCH] iscsi-target: fix panic when add the second TCP connection to iSCSI session

2016-07-11 Thread 冯力

This problem exists at least from v3.16.
The upstream kernel still exists this issue.

I have tested my patch and the following panic is disappeared.

Thanks,

[PATCH] fs/cepth compile error

2013-06-10 Thread 冯力

I try to compile kernel v3.9.2 v3.9.5, It outputs couldn't find fs/cepth/ioctl.o
Go to the dir and couldn't find the ioctl.c,only a ioctl.h file.But
the ioctl.h isn't included by other file.
So simply remove ioctl.o from the Makefile to fix.

Thanks
