Not True. Once again, (wink) it is the VFS layer, NOT ext2. And
furthermore, it is the ext2 layer on intel 32 bit machines. Any Linux FS
on any kernel less than 2.4, without a special, mostly operational
patch, will not do >2GB files.

While I love XFS on Linux, You do not need it to get LF support. it is in the 2.4 kernel's newer VFS.

A recompile with the newer glibc and Kernel fixes most of these issues,
though I can not at this time, say it fixes them all.
(I can say I have yet to have any issues with 15 or even 500 GB files on
RH 7.1 with XFS.
