Subject: f2fs: allow checkpoint=disable for zoned block device
X-Git-Tag: v6.8-rc1~112^2~21
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=29215a7d43c77466f2d7e6c264942e6bc8e06cd8;p=thirdparty%2Fkernel%2Flinux.git

f2fs: allow checkpoint=disable for zoned block device

Let's allow checkpoint=disable back for zoned block device. It's very risky
as the feature relies on fsck or runtime recovery which matches the write
pointers again if the device rebooted while disabling the checkpoint.
