This patch synthesize PERF_RECORD_KSYMBOL and PERF_RECORD_BPF_EVENT for
BPF programs loaded before perf-record. This is achieved by gathering
information about all BPF programs via sys_bpf.

For better performance analysis of BPF programs, this patch introduces
PERF_RECORD_BPF_EVENT, a new perf_event_type that exposes BPF program
load/unload information to user space.
Each BPF program may contain up to BPF_MAX_SUBPROGS (256) sub programs.
The following example shows kernel symbols for

For better performance analysis of dynamically JITed and loaded kernel

PERF_RECORD_KSYMBOL, a new perf_event_type that exposes kernel symbol

The following data structure is used for PERF_RECORD_KS
This patch handles PERF_RECORD_KSYMBOL in perf record/report.
Specifically, map and symbol are created for ksymbol register, and
removed for ksymbol unregister.
This patch also set perf_event_attr.ksymbol properly. The flag is

Change snprintf to scnprintf. There are generally two cases where using
snprintf causes problems.
1) Uses of size += snprintf(buf, SIZE - size, fmt, ...) In this case,
if snprintf would have written more characters than what the buffer
size (SIZE) is, then size will end up larger than SIZE. In la
Handling short packets (length < max packet size) in the Inventra DMA
engine in the MUSB driver causes the MUSB DMA controller to hang. An

This is the reason. The adv7180 is only allowing to configure

Dear RT Folks,
I'm pleased to announce the 4.14.93-rt53 stable release.
This release is just an update to the new stable 4.14.93 version
and no RT specific changes have been made.
You can get this release via the git tree at:
git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-r
We don't do page cache reparent anymore when offlining memcg, so update
force empty related content accordingly.
