[PATCH v5 0/2] libceph: reject zero bucket types and clean up type 0 uses

[Ren Wei <n05ec@lzu.edu.cn>]

From: Douya Le <ldy3087146292@gmail.com>

This series fixes a CRUSH map decode issue in libceph and keeps the
follow-up type-0-to-constant cleanup in a separate patch.

Patch 1/2 rejects bucket type 0 during CRUSH map decode and defines the
reserved device type in a separate enum.

Patch 2/2 uses that type constant consistently in the CRUSH mapper
paths that identify leaf devices.

Douya Le (2):
  libceph: reject zero bucket types in crush_decode
  libceph: crush: use CRUSH_ITEM_TYPE_DEVICE for leaf device checks
