From: Eric Biggers <redacted> Add FS_VERITY_FL to the flags for FS_IOC_GETFLAGS, so that applications can easily determine whether a file is a verity file at the same time as they're checking other file flags. This flag will be gettable only; FS_IOC_SETFLAGS won't allow setting it, since an ioctl must be used instead to provide more parameters. This flag matches the on-disk bit that was already allocated for ext4. Reviewed-by: Theodore Ts'o <tytso@mit.edu>
