Subject: [PATCH 23/41] Manage: fix check after dereference issue
|
|
|
|
The code dereferences dev_st earlier without checking, it gives SAST
|
|
problem.
|
|
|
|
dev_st is needed for attempt_re_add(), but it is executed only if
|
|
dv->disposition != 'S', so move disposition check up.
|
|
|
|
tst is a must to reach this place, dup_super() have to return valid
|
|
pointer, all it needs to check is if load_super() returns superblock.
