Fix build errors with linux kernel v3.19 and above
|
||||
|
||||
Below errors came up while building iscsitarget for
|
||||
qemux86-64 (and others) because,
|
||||
1. 'struct user_msghdr' is being used for userland-side msghdr instead
|
||||
of 'struct msghdr', which is used for kernel-side msghdr in linux v3.19
|
||||
and above.

||||

|

2. 'SERVICE_ACTION_IN' has been renamed to SERVICE_ACTION_IN_16 in linux v3.19
|

3. In linux v3.19 and above, f_dentry member has been removed from
|
||||
'struct file' structure.
