Revision 0fb9a1abc8c97f858997e962694eb36b4517144e authored by Mathieu Desnoyers on 09 July 2018, 19:51:52 UTC, committed by Thomas Gleixner on 10 July 2018, 20:18:52 UTC
Update rseq uapi header comments to reflect that user-space need to do thread-local loads/stores from/to the struct rseq fields. As a consequence of this added requirement, the kernel does not need to perform loads/stores with single-copy atomicity. Update the comment associated to the "flags" fields to describe more accurately that it's only useful to facilitate single-stepping through rseq critical sections with debuggers.
