[PATCH v2 2/2] MAINTAINERS: add section for locking of mm's and VMAs
Posted by Lorenzo Stoakes 8 months, 1 week ago 
We place this under memory mapping as related to memory mapping
abstractions in the form of mm_struct and vm_area_struct (VMA). Now we have
separated out mmap/vma locking logic into the mmap_lock.c and mmap_lock.h
files, so this should encapsulate the majority of the mm locking logic in
the kernel.

Suren is best placed to maintain this logic as the core architect of VMA
locking as a whole.
