From 5a80d1c6a2704d880c1df30315a1d9b0dc1f2cd8 Mon Sep 17 00:00:00 2001 From: Johannes Thumshirn Date: Tue, 29 Jun 2021 03:36:45 +0900 Subject: btrfs: zoned: remove max_zone_append_size logic There used to be a patch in the original series for zoned support which limited the extent size to max_zone_append_size, but this patch has been dropped somewhere around v9. We've decided to go the opposite direction, instead of limiting extents in the first place we split them before submission to comply with the device's limits. Remove the related code, btrfs_fs_info::max_zone_append_size and btrfs_zoned_device_info::max_zone_append_size. This also removes the workaround for dm-crypt introduced in 1d68128c107a ("btrfs: zoned: fail mount if the device does not support zone append") because the fix has been merged as f34ee1dce642 ("dm crypt: Fix zoned block device support").
