Linux 2.6.36 compat, sops->evict_inode() The new prefered inteface for evicting an inode from the inode cache is the ->evict_inode() callback. It replaces both the ->delete_inode() and ->clear_inode() callbacks which were previously used for this.

Improve HAVE_EVICT_INODE check The hardened gentoo kernel defines all of the super block operation callbacks as const. This prevents the autoconf test from assigning the callback and results in a false negative. By moving the assignment in to the declaration we can avoid this issue and get a correct result for this patched kernel. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #296
