[PATCH 0/4] xfsdump: convert to using the POSIX signal API

[Christoph Hellwig]

Bill,

one thing I noticed looking over the code to understand your changes
is that there still is a lot of dead code in xfsdump.  One that
has a lot of implications and seems fairly useless for any non-IRIX
version is the miniroot mode.  Any chance we can rip that out?  There's
also a lot of code under #ifdef HIDDEN - it would be good to go through
these and see we can just be removed, and if anything is still useful
moved under more self-explaining ifdefs.
