Carlos Galo 6b4c816d17 FROMGIT: BACKPORT: mm: update mark_victim tracepoints fields
The current implementation of the mark_victim tracepoint provides only the
process ID (pid) of the victim process.  This limitation poses challenges
for userspace tools that need additional information about the OOM victim.
The association between pid and the additional data may be lost after the
kill, making it difficult for userspace to correlate the OOM event with
the specific process.

In order to mitigate this limitation, add the following fields:

- UID
   In Android each installed application has a unique UID. Including
   the `uid` assists in correlating OOM events with specific apps.

- Process Name (comm)
   Enables identification of the affected process.

- OOM Score
   Allows userspace to get additional insights of the relative kill
   priority of the OOM victim.
