Naohiro Aota 0b214ccbc7 btrfs: zoned: wait for data BG to be finished on direct IO allocation ... commit 776a838f1f upstream. Running the fio command below on a ZNS device results in "Resource temporarily unavailable" error. $ sudo fio --name=w --directory=/mnt --filesize=1GB --bs=16MB --numjobs=16 \ --rw=write --ioengine=libaio --iodepth=128 --direct=1 fio: io_u error on file /mnt/w.2.0: Resource temporarily unavailable: write offset=117440512, buflen=16777216 fio: io_u error on file /mnt/w.2.0: Resource temporarily unavailable: write offset=134217728, buflen=16777216 ... This happens because -EAGAIN error returned from btrfs_reserve_extent() called from btrfs_new_extent_direct() is spilling over to the userland. btrfs_reserve_extent() returns -EAGAIN when there is no active zone available. Then, the caller should wait for some other on-going IO to finish a zone and retry the allocation. This logic is already implemented for buffered write in cow_file_range(), but it is missing for the direct IO counterpart. Implement the same logic for it.
