This series addresses a few issues in the trace remote buffers allocation
and descriptor handling, mostly reported by Sashiko bot on top of v1.

Changelog:

v1 -> v2:
  - Leak fix: increment nr_cpus early (after meta_va allocation) instead of
    in the error path.
  - Added struct_len double-counting fix.
  - Added sparse CPU masks support in ring_buffer_desc().

v1: https://lore.kernel.org/all/20260708133201.295072-1-vdonnefort@google.com/ (local)

Vincent Donnefort (3):
  tracing/remotes: Fix leak in trace_remote_alloc_buffer() error path
  tracing/remotes: Fix struct_len in trace_remote_alloc_buffer()
  ring-buffer: Allow sparse CPU masks in ring_buffer_desc()
