Merge branch 'introduce bpf_find_vma'
Song Liu says:
====================
Changes v4 => v5:
1. Clean up and style change in 2/2. (Andrii)
Changes v3 => v4:
1. Move mmap_unlock_work to task_iter.c to fix build for .config without
!CONFIG_PERF_EVENTS. (kernel test robot <lkp@intel.com>)
Changes v2 => v3:
1. Avoid using x86 only function in selftests. (Yonghong)
2. Add struct file and struct vm_area_struct to btf_task_struct_ids, and
use it in bpf_find_vma and stackmap.c. (Yonghong)
3. Fix inaccurate comments. (Yonghong)
Changes v1 => v2:
1. Share irq_work with stackmap.c. (Daniel)
2. Add tests for illegal writes to task/vma from the callback function.
(Daniel)
3. Other small fixes.
Add helper bpf_find_vma. This can be used in some profiling use cases. It
might also be useful for LSM.
