Fix build failures on PaX/GRSecurity patched kernels
Gentoo Hardened kernels include the PaX/GRSecurity patches. They use a dialect of C that relies on a GCC plugin. In particular, struct file_operations has been marked do_const in the PaX/GRSecurity dialect, which causes GCC to consider all instances of it as const. This caused failures in the autotools checks and the ZFS source code. To address this, we modify the autotools checks to take into account differences between the PaX C dialect and the regular C dialect. We also modify struct zfs_acl's z_ops member to be a pointer to a function pointer table. Lastly, we modify zpl_put_link() to address a PaX change to the function prototype of nd_get_link(). This avoids compiler errors in the PaX/GRSecurity dialect. Note that the change in zpl_put_link() causes a warning that becomes a build failure when debugging is enabled. Fixing that warning requires ryao/spl@5ca50ef459. Signed-off-by: Richard Yao <ryao@cs.stonybrook.edu> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #484
