[Pvfs2-developers] Long file names

[Phil Carns]

Hi Bart,

I can't get those specific commands to cause a problem for me (using 
trunk at least, I haven't tried 2.7.1 yet).  However, I definitely see 
some problems in LTP.  For me it eventually hangs on the rename06 test, 
but valgrind is complaining about some memory problems in the 
pvfs2-client-core symlink path as well before reaching that point.

I'll look into it and let you know what turns up.

I might also see if I can cook up a script to include LTP in our nightly 
tinderbox builds as well; there are some good tests in here.
