The osd driver was accepted in the upstream kernel in 2009. I have checked all
commits in Linus' tree for the osd driver that went in since 2009. All changes
made by other kernel developers than you are the result of tree-wide refactoring,
compiler warning fixes, fixes for issues detected by static source code
analyzers or spelling fixes. Hence my question: how big is the user base of the
exofs and osd kernel drivers?
Thanks,
Bart.
