Is it also known, (and the same bug) when you get the lock warnings when 
doing
"xfs_restore", as well (dio_get_page and xfs_ilock)...

Doesn't give me the warm & fuzzies, but I'm sure you've heard that 
sentiment plenty
of times...

The bugs with 'sort', & imap were both with xfs_ilock and 
shrink_icache_memory.

I saw another bug (different prog) with those two locks that was said to 
be a bug in
XFS by Andrew Morton, but he didn't say if it was the same known 
"harmless" "bug" or
if it was more serious.
