Fix a deadlock in LockSettingsService
Order of taking locks in LSS: mSeparateChallengeLock -> mSpManager -> this.
Since getGateKeeperService().getSecureUserId() will end up calling
getSeparateProfileChallengeEnabled() which tries to acquire mSeparateChallengeLock
, we shouldn't be holding this lock while calling getSecureUserId()
Also spell out the order of taking locks in a comment.
Test: while device lockscreen is being changed, run "adb shell dumpsys lock_settings"
and verify device is not locked up.
