[PATCH v2 08/18] zonefs: convert iomap ops to ->iomap_next()

From: Joanne Koong

Date: Tue Jun 30 2026 - 20:14:15 EST


Convert zonefs iomap_ops to the new ->iomap_next() callback. This uses the
iomap_process() helper, which finishes the previous mapping if needed
and produces the next one. No functional changes are intended.
