Return to io.h CVS log

Up to [Development] / xfs-cmds / xfsprogs / io

Move lsattr/chattr commands into separate file, we need to add some more options here soon for IRIX so these are getting enough code to warrant separate sources.  No functional change.
Merge of xfs-cmds-melb:slinx:19483a by kenmcd.
