./configure erroneously detects absence of dops->d_automount when built against a GrSecurity patched kernel. Summerized error message found in config.log: checking whether dops->d_automount() exists ... In function 'main': ... error: constified variable 'dops' cannot be local The "dops" variable cannot be a local variable, so it's moved to the global scope. This test also fails if the prototype of the dops->d_automount function pointer is changed. Signed-off-by: Massimo Maggi <massimo@mmmm.it> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Richard Yao <ryao@cs.stonybrook.edu> Closes #884
