statx: define STATX_ATTR_VERITY
Add a statx attribute bit STATX_ATTR_VERITY which will be set if the file has fs-verity enabled. This is the statx() equivalent of FS_VERITY_FL which is returned by FS_IOC_GETFLAGS. This is useful because it allows applications to check whether a file is a verity file without opening it. Opening a verity file can be expensive because the fsverity_info is set up on open, which involves parsing metadata and optionally verifying a cryptographic signature. This is analogous to how various other bits are exposed through both FS_IOC_GETFLAGS and statx(), e.g. the encrypt bit. Reviewed-by: Andreas Dilger <adilger@dilger.ca> Acked-by: Darrick J.
