In the Linux kernel, the following vulnerability has been resolved: btrfs: zoned: don't force read-only on transient -EAGAIN from reloc merge On a zoned FS, btrfs_delayed_refs_rsv_refill() returns -EAGAIN whenever the over-committed metadata plus the zone_unusable bytes exceeds the usable size in a metadata block-group to avoid heavy over-commit of metadata and early ENOSPC in one transaction. If this happens while doing reclaim, the transaction is getting aborted. Treat -EAGAIN as a soft, retryable condition in case of block-group reclaim.
