From dc1b17a25c321c8f1b4f90f9d6f8afb1d132b69c Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 22 Apr 2024 13:20:13 +0200 Subject: xfs: reinstate RT support in xfs_bmapi_reserve_delalloc Allocate data blocks for RT inodes using xfs_dec_frextents. While at it optimize the data device case by doing only a single xfs_dec_fdblocks call for the extent itself and the indirect blocks.
