Subject: [PATCH] btrfs-progs: zoned: make it work without kernel support
|
||||
|
||||
There's a report that a system with 4.19 kernel fails boot because
|
||||
device scan exits with error. This is because zoned support is compiled
|
||||
in btrfs-progs but not in kernel.
|
||||
|
||||
To make new progs and old kernels work, do a fallback when the zoned
|
||||
ioctl is not available, as if it were a non-zoned device. There is no
|
||||
other option, but this is safe at least for the device scan that would
|
||||
not error out. Any unaligned writes to a zoned device will fail as
|
||||
expected.
|
||||
|
||||
Issue: #376
