Subject: [PATCH 556/686] lslogins: remove duplicate NULL check
|
||
|
|
|
||
|
|
Having this excess NULL check in place causes small performance penalty, and
|
||
|
|
makes compiler to guess wrong if a null should be checked. To me getting
|
||
|
|
rid of false positive warning is more useful.

login-utils/lslogins.c:634:7: warning: potential null pointer dereference
|
||
|
|
[-Wnull-dereference]
