It is a direct replacement of the patch 3 in discussion [1]
and to test out the idea on adding
map_local_storage_charge, map_local_storage_uncharge,
and map_owner_storage_ptr.
It is only compiler tested to demo the idea.
[1]:
Since syzkaller continues various test cases until the kernel crashes,
syzkaller tends to examine more locking dependencies than normal systems.
As a result, syzbot is reporting that the fuzz testing was terminated
due to hitting upper limits lockdep can track [1] [2] [3].

Hello folks,
I've been poking around the shmem/tmpfs code with an eye towards
adding reflink support to tmpfs.
Prior to looking at the code, conceptually I was envisioning the pages
in the reflink source inode's address_space would simply get their
refcounts bumped as they were added to the dest
The driver function tg3_io_error_detected() calls napi_disable twice,
without an intervening napi_enable, when the number of EEH errors exceeds
eeh_max_freezes, resulting in an indefinite sleep while holding rtnl_lock.
Add check for pcierr_recovery which skips code already executed for the
PCI fixes:
- Reject invalid IRQ 0 command line argument for virtio_mmio because
IRQ 0 now generates warnings (Bjorn Helgaas)
- Revert "PCI/PM: Assume ports without DLL Link Active train links
in 100 ms", which broke nouveau (Bjorn Helgaas)

Do not use rlimit-based memory accounting for bpf ringbuffer.
It has been replaced with the memcg-based memory accounting.
bpf_ringbuf_alloc() can't return anything except ERR_PTR(-ENOMEM)
and a valid pointer, so to simplify the code make it return NULL
in the first case. This allows to drop a
Enable the memcg-based memory accounting for the memory used by
the bpf ringbuffer.

Since bpf is not using rlimit memlock for the memory accounting
and control, do not change the limit in sample applications.

Since bpf stopped using memlock rlimit to limit the memory usage,
there is no more reason for bpftool to alter its own limits.

As rlimit-based memory accounting is not used by bpf anymore,
there are no more reasons to play with memlock rlimit.
Delete bpf_rlimit.h which contained a code to bump the limit.

As bpf is not using memlock rlimit for memory accounting anymore,
let's remove the related code from libbpf.
Bpf operations can't fail because of exceeding the limit anymore.
