Mark's v4 dirent patches seem to work on 32-bit x86.  I happen to agree 
100% with Dave on this issue.  However, lacking a dirent test and 
xfs_db skills, I threw everything else and the kitchen sink at 
v4-dirent XFS and did not find any evidence to back up Dave's argument. 
So I'll tip my cap to Mark for his insight on the matter, hoping that 
his testing skills are fine as always.

Thanks!
