[PATCH v2 2/2] selftests: liveupdate: Add tests for LIVEUPDATE_SESSION_FREEZE

[sashiko-bot at kernel.org]

> Provide luo_session_freeze() in the liveupdate test library and add unit
> tests in liveupdate.c covering the LIVEUPDATE_SESSION_FREEZE ioctl. The
> tests verify that non-zero reserved bits are rejected with -EINVAL, an
> outgoing session with preserved files can be frozen early, freezing an
> already frozen session returns -EBUSY, and attempting to preserve an
> additional file descriptor into a frozen session fails with -EBUSY.
> 
> Also freeze the test session early in luo_kexec_simple.c to exercise
> LIVEUPDATE_SESSION_FREEZE across a kexec reboot, and verify that
> attempting to freeze a retrieved incoming session returns -EINVAL.
