Subject: [PATCH] setcifsacl: fix bad bit-shift in raw_str_to_sid
|

MIME-Version: 1.0

A Coverity scan turned up this warning:
|
||
|
||
1. cifs-utils-6.2/setcifsacl.c:578:result_independent_of_operands – "(x & 0xff0000000000ULL) >> 48" is 0 regardless of the values of its operands. This occurs as the operand of assignment.
|
||
|
||
...which is entirely true. That shift should be 40 bits, not 48.
