As a debugging feature, report the absolute pathname of the plug-in library that mountd loads to resolve junctions. Since mountd passes a relative path to dlopen(3), dlopen(3) must search for the right library. Displaying the absolute pathname of the object that it found verifies that mountd loaded the correct plug-in. Note: dlinfo(3) is provided by libdl, but there doesn't seem to be a man page on Fedora 16 for dlinfo(3). Instead, see: http://www.unix.com/man-page/all/3/dlinfo/ Signed-off-by: Chuck Lever <chuck.lever@oracle.com> --- utils/mountd/cache.c | 7 +++++++ 1 files changed, 7 insertions(+), 0 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
