[lustre-devel] [PATCH 607/622] lustre: uapi: remove unused LUSTRE_DIRECTIO_FL

[James Simmons]

From: Andreas Dilger <adilger at whamcloud.com>

The LUSTRE_DIRECTIO_FL was added based on the upstream FS_DIRECTIO_FL
flag in the hopes that it might be useful, but it has since been
removed from the upstream in kernel commit v4.4-rc4-22-g68ce7bfcd995
and replaced by FS_VERITY_FL using the same value in kernel commit
v5.3-rc2-4-gfe9918d3b228, which we are much more likely to use.

Since LUSTRE_DIRECTIO_FL was unused, there is no risk to remove it.
