CVE-2026-90266

btrfs: zoned: don't force read-only on transient -EAGAIN from reloc merge

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.
