From 7099bd0f243fa7511de6e95b0b8807ba7d3e5204 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 22 Apr 2024 13:20:15 +0200 Subject: xfs: support RT inodes in xfs_mod_delalloc To prepare for re-enabling delalloc on RT devices, track the data blocks (which use the RT device when the inode sits on it) and the indirect blocks (which don't) separately to xfs_mod_delalloc, and add a new percpu counter to also track the RT delalloc blocks.
