-Subject: [PATCH] fix: mm: introduce vma->vm_flags wrapper functions (v6.3)
-
-See upstream commit :
-
- commit bc292ab00f6c7a661a8a605c714e8a148f629ef6
- Author: Suren Baghdasaryan <surenb@google.com>

-
- mm: introduce vma->vm_flags wrapper functions
-
- vm_flags are among VMA attributes which affect decisions like VMA merging
- and splitting. Therefore all vm_flags modifications are performed after
- taking exclusive mmap_lock to prevent vm_flags updates racing with such
- operations. Introduce modifier functions for vm_flags to be used whenever
- flags are updated. This way we can better check and control correct
- locking behavior during these updates.

- uuid: Decouple guid_t and uuid_le types and respective macros
-
- The guid_t type and respective macros are being used internally only.
- The uuid_le has its user outside the kernel. Decouple these types and
- macros, and make guid_t completely internal type to the kernel.

- btrfs: pass find_free_extent_ctl to allocator tracepoints
-
- The allocator tracepoints currently have a pile of values from ffe_ctl.
- In modifying the allocator and adding more tracepoints, I found myself
- adding to the already long argument list of the tracepoints. It makes it
- a lot simpler to just send in the ffe_ctl itself.
