In general I like this, but:
- please provide a testcase actually using this new feature, and
- please don't require e2fsprogs just for the ioctl subcommands,
and use the FS_IOC_GET/SETFLAGS names provided by recent kernels
in fs.h instead. You might still need an ifdef for old kernels,
like src/t_immutable.c does. In fact it might be a good idea
to just provide the values for them if they aren't present in
a header shared by fsstress and t_immutable.c
