Subject[PATCH v2 0/3] rseq: minor optimizations
Date
From: Eric Dumazet <edumazet@google.com>

rseq is a heavy user of copy to/from user data in fast paths.
This series tries to reduce the cost.

v2: Addressed Peter and Mathieu feedbacks, thanks !

Eric Dumazet (3):
rseq: optimize rseq_update_cpu_id()
rseq: remove redundant access_ok()
rseq: optimise rseq_get_rseq_cs() and clear_rseq_cs()
