Hi David, hi Jakub, hi Paolo, hi Eric,

The following pull-request contains BPF updates for your *net* tree.

We've added 19 non-merge commits during the last 10 day(s) which contain
a total of 20 files changed, 738 insertions(+), 448 deletions(-).

The main changes are:

1) Batch of BPF sockmap fixes found when running against NGINX TCP tests, from John Fastabend.

2) Fix a memleak in the LRU{,_PERCPU} hash map when bucket locking fails, from Anton Protopopov.

3) Init the BPF offload table earlier than just late_initcall, from Jakub Kicinski.

4) Fix ctx access mask generation for 32-bit narrow loads of 64-bit fields, from Will Deacon.

5) Remove a now unsupported __fallthrough in BPF samples, from Andrii Nakryiko.

6) Fix a typo in pkg-config call for building sign-file, from Jeremy Sowden.
