----------------------------------------------

Hi Daryn,

Given there are so many incompatible changes in 0.23, I favor posix compliant.

BTW, your patch is stale.  Could you update it?

> mkdirs should use the supplied permission for all of the created directories

> Mkdirs only uses the supplied FsPermission for the last directory of the 
> path.  Paths 0..N-1 will all inherit the parent dir's permissions -even if- 
> inheritPermission is false.  This is a regression from somewhere around 
> 0.20.9 and does not follow posix semantics.
