[lustre-discuss] Lustre Client on Fedora 23

[Michael Watters]

Thanks.  It looks like the checkpatch.pl script has already been updated 
however I did have to change the lustre/osd-ldiskfs/osd_io.c 
b/lustre/osd-ldiskfs/osd_io.c file which contained two references to the 
old function names.

make is now failing with a different error as shown below.

Any idea how to fix this?
