Description Chris Lalancette 2006-08-25 09:54:06 EDT

Description of problem:
When starting up the oprofile daemon via "opcontrol --start --verbose", if any
component of the file names being profiles have path names > NAME_MAX (which
happens to be 255 on RHEL3), oprofiled will fail with a ENAMETOOLONG.  While
this is a limitation of the path names, it might make sense to detect when names
are too long, and use some sort of hash to shorten them up.  I assume this would
also be the case if the entire path was > PATH_MAX (which is 4096 in RHEL3), but
I have not tested that to confirm.
