Merge patch series "io_uring / dio metadata fixes"
Christoph Hellwig <hch@lst.de> says:
Hi all,
while trying to add XFS support for passing through metadata I ran
into a few issues with how that support is wire up for the current
block device use cases, and this fixes it.
* patches from https://lore.kernel.org/20250819082517.2038819-1-hch@lst.de:
block: don't silently ignore metadata for sync read/write
fs: add a FMODE_ flag to indicate IOCB_HAS_METADATA availability
