The rte_eal_get_runtime_dir() function is currently being declared in two header files. This API was made public in commit6911c9fd8f("eal: export function to get runtime directory"), adding it to rte_eal.h. To make it public, the 'rte' prefix was added to the function so it needed to be modified in the original location of the declaration, eal_filesystem.h. By only modifying, and not removing the decalration, it is now a duplicate. This patch removes the declaration from eal_filesystem.h. Fixes:6911c9fd8f("eal: export function to get runtime directory") Reported-by: Anatoly Burakov <anatoly.burakov@intel.com> Signed-off-by: Kevin Laatz <kevin.laatz@intel.com> Acked-by: Anatoly Burakov <anatoly.burakov@intel.com>
