Re: [Gluster-devel] [write-beind] why we don't cache if length of data can not be divided by 4096.

[Anand Avati]

Li,
 this is legacy code from the time when the inode framework was not around,
and multiple fds and plain calls on filenames could not be related. back
then the aggregate-size was used as a mean to aggregate only broken writes
of fuse. I guess we can remove this piece of code now though it actually
causes no "harm".
