From afc04c8b1bb5552e6f7e05b4fe02ebc451fe66ff Mon Sep 17 00:00:00 2001 From: Qu Wenruo Date: Mon, 27 Oct 2025 18:58:47 +1030 Subject: [PATCH] btrfs: replace BTRFS_MAX_BIO_SECTORS with BIO_MAX_VECS It's impossible to have a btrfs bio with more than BIO_MAX_VECS vectors anyway. And there is only one location utilizing that macro, just replace it with BIO_MAX_VECS. Both have the same value.
