== How CRIU handles rseq ==

== Checkpoint/Restore of RSEQ ==

CRIU handles the rseq differently depending on the particular case. Let's classify and cover all of them.

CRIU handles restartable sequences differently depending on the execution state of the process at checkpoint time. This can be categorized into the following cases:

# the process is not inside the rseq critical section

# Process is not executing inside an rseq critical section

# the process is inside the rseq CS

# Process is executing inside an rseq critical section

## <code>flags</code> is <code>0</code> or <code>RSEQ_CS_FLAG_NO_RESTART_ON_PREEMPT</code> or <code>RSEQ_CS_FLAG_NO_RESTART_ON_MIGRATE</code>

## <code>flags</code> is <code>0</code>, <code>RSEQ_CS_FLAG_NO_RESTART_ON_PREEMPT</code>, or <code>RSEQ_CS_FLAG_NO_RESTART_ON_MIGRATE</code>

## <code>flags</code> is <code>RSEQ_CS_FLAG_NO_RESTART_ON_SIGNAL</code>

## <code>flags</code> includes <code>RSEQ_CS_FLAG_NO_RESTART_ON_SIGNAL</code>
