Hello Oleg,
As far as I know the tcmu_opcode enum type is not used anywhere as a
member of a struct. So why is the explicit size specification needed ?
static inline enum tcmu_opcode tcmu_hdr_get_op(__u32 len_op)
{
- return len_op & TCMU_OP_MASK;
+ return (tcmu_opcode)(len_op & TCMU_OP_MASK); // note, an
explicit conversion is needed
+ // in C++11 and higher
}
C compilers will report a syntax error for the above code. Please reread
my previous e-mail.
Bart.
