( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/442394 Change subject: RFC: [do not merge] (lib)ganesha_nfsd as a DSO ...................................................................... RFC: [do not merge] (lib)ganesha_nfsd as a DSO Build ganesha as a DSO, i.e. libganesha_nfsd.so. Take No. Two-dot-one, addressing comments from the first go-around. The ganesha.nfsd daemon consists of just nfs_main:main() and is linked with the DSO. Then all the FSALs (except FSAL_PSEUDO and FSAL_MDCACHE*) are linked with libganesha_nfsd resolution of functions in ganesha.nfsd itself. This will be required if, e.g., Fedora, decides to require default linking with '-z defs'. They tried to do it for F29 but retreated when they found that too many applications broke. In the end this may all be just an exercise in "truth and beauty." *FSAL_PSEUDO and FSAL_MDCACHE are special; they are included in the DSO so do not need to be (and can't be) linked with the DSO. A few other things that could be done are 1) link libganesha_nfsd.so with a .sym file to explicitly control which symbols are exposed or visible to the outside world. 2) build with -flto (Link Time Optimization) Annecdotes claim a 5-10% speed improvement is typical, and some applications have seen as much as 45-50% boost. Of course we have to do the experiment to see what we really achieve. 3) don't link ganesha.nfsd with -bdynamic as it's no longer needed Signed-off-by: Kaleb S.
