[PATCH bpf v2 0/2] Fix bpf_link grace period wait for tracepoints

[Kumar Kartikeya Dwivedi <memxor@gmail.com>]

A recent change to non-faultable tracepoints switched from
preempt-disabled critical sections to SRCU-fast, which breaks
assumptions in the bpf_link_free() path. Use call_srcu() to fix the
breakage. While at it, retire rcu_trace_implies_rcu_gp() and clean up
all in-tree users.

Changelog:
----------
v1 -> v2
