Subject: [PATCH] fs: btrfs: Disable BTRFS on platforms having 256K pages
Date: Thu, 10 Jun 2021 05:23:02 +0000 (UTC) [thread overview]
Message-ID: <a16c31f3caf448dda5d9315e056585b6fafc22c5.1623302442.git.christophe.leroy@csgroup.eu> (raw)
With a config having PAGE_SIZE set to 256K, BTRFS build fails
with the following message
include/linux/compiler_types.h:326:38: error: call to '__compiletime_assert_791' declared with attribute error: BUILD_BUG_ON failed: (BTRFS_MAX_COMPRESSED % PAGE_SIZE) != 0
BTRFS_MAX_COMPRESSED being 128K, BTRFS cannot support platforms with
256K pages at the time being.
There are two platforms that can select 256K pages:
- hexagon
- powerpc
Disable BTRFS when 256K page size is selected.
