[Moosefs-users] help to explain the function of fsedge data structure in mfsmaster/filesystem.c

[yishi c. <hol...@gm...>]

hi mfs-developer：
                        recently I‘ve been reading the source code of
moosefs,but be confused of the function of  fsedge data structure.Is there
anybody who is willing to answer the following quz:

                        1,this structure seems to link the children fsnode
with the parent dir.since there is no notation for this part of code，can
the developer explain the function of this structure in detail.

                        2,I think the nextchild and nextparent point to
itself.and the prevchild/prevparent seems to point to itself as well.is it
correct.if so,why moosefs need this?



                        Best regard
