Subject: [PATCH 06/12] fs/ceph: consistently use `u32` for `time_warp_seq`
Date: Fri, 12 Jun 2026 18:51:58 +0200	[thread overview]
Message-ID: <20260612165204.86137-7-max.kellermann@ionos.com> (raw)
In-Reply-To: <20260612165204.86137-1-max.kellermann@ionos.com>

Previously, both `u32` and `u64` was used with implicit casts.  All
this does is add useless overhead.

This will allow better struct packing in `struct ceph_cap_snap`.
