mount/nfs_mount4.h

   1 /*
   2  * We want to be able to compile mount on old kernels in such a way
   3  * that the binary will work well on more recent kernels.
   4  * Thus, if necessary we teach nfsmount.c the structure of new fields
   5  * that will come later.
   6  *
   7  * Moreover, the new kernel includes conflict with glibc includes
   8  * so it is easiest to ignore the kernel altogether (at compile time).
