[NFS-Ganesha-Support] Unsupported FSALs

Community, We have a number of FSALs in Ganesha that have no effective support, I'd like to understand who might still be relying on them and if there is anyone who might step up to support them, or whether we can consider removing some on an expedited timeline (normally we declare a FSAL is deprecated in one release, and then remove it in the next). Note that with the magic of git, deleted FSALs could easily be resurrected (though they might not have been updated to match API changes). The risk of not removing unsupported code is first that folks will use code with little or no support and open github issues that cannot effectively be addressed, and that unsupported code may not be properly updated as API changes are made. The following FSALs are suspect: src/FSAL/FSAL_VFS/xfs - this is marginally supported, but could be replaced with plain FSAL_VFS src/FSAL/FSAL_VFS - there is also a Lustre FSAL that is built from this src/FSAL/FSAL_GLUSTER src/FSAL/FSAL_LIZARDFS src/FSAL/FSAL_PROXY_V3 src/FSAL/FSAL_PROXY_V4 src/FSAL/FSAL_KVSFS src/FSAL/FSAL_SAUNAFS Thank for your thoughts Frank Filz
