The reasons to not do file I/O from inside the kernel are many and well
documented.  Of course, if you're trying to do something like unionfs
or fuse, you may not have a choice.

And if you're doing something like that, it is probablly better to *avoid*
using the sys_* calls even if they are available, but instead use filp_open()
and the vfs_ functions.
