Revision 50e43a57334400668952f8e551c9d87d3ed2dfef authored by Al Viro on 25 July 2021, 17:19:45 UTC, committed by Geert Uytterhoeven on 24 September 2021, 11:35:01 UTC
We get there when sigreturn has performed obscene acts on kernel stack; in particular, the location of pt_regs has shifted. We are about to call syscall_trace(), which might stop for tracer.
