[PATCH v1 2/7] 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 an outgoing session with preserved files can be frozen
> early, that freezing an already frozen session returns -EBUSY, and that
> 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.
