(13) FS_IOC_GETFLAGS value.  These could be translated to BSD's st_flags.
     Note that the Linux IOC flags are a mess and filesystems such as Ext4
     define flags that aren't in linux/fs.h, so translation in the kernel
     may be a necessity (or, possibly, we provide the filesystem type too).

And we now also have FS_IOC_FSGETXATTR that extends the flags
and information userspace can get from filesystems.

Btw, can you point me at the manpage that defines the fsxattr struct and its
flags?

man xfsctl is the original source. However, ....

Also, ioctl_list(2) should probably include FS_IOC_FS[GS]ETXATTR.

... I thought patches had been sent to Michael to document them at
the VFS ioctl level. maybe I confused it with something else.....

Cheers,

Dave.
