d51053c5d9 It's wrong to clean reservation on failed RESERVE commands 
With multiple outstanding commands it can open a race window leading to
loose of a valid reservation

23250756c2 isert: Handle TargetRecvDataSegmentLength in RFC compliant way 
iSER RFC defines TargetRecvDataSegmentLength to be mandatory.
Also, according to the RFC, the target must be prepared to receive at least 512 bytes,

6b020ed078 scst: Avoid that smatch complains about dead code 
The panic() function that implements BUG() has been declared with attribute
noreturn in some RHEL 5 kernel headers and also in the RHEL 6 kernel headers.
Smatch warns about dead code if any code follows a function that has been
declared with attribute noreturn. Hence add a few preprocessor statements to
suppress the smatch warning when building against an upstream kernel or when
building against RHEL 6 or later.
