# HEAD: dc0a241ceaf3b7df6f1a7658b020c92682b75bfc rseq: Fix rseq registration with CONFIG_DEBUG_RSEQ

Two RSEQ fixes:

- Fix overly spread-out RSEQ concurrency ID allocation pattern that
regressed certain workloads.

- Fix RSEQ registration syscall behavior on -EFAULT errors when
CONFIG_DEBUG_RSEQ=y. (This debug option is disabled on most
distributions.)

Thanks,

Ingo
