[issue1129] hammer-inodes: malloc limit exceeded

[Matthew Dillon]

:It is a single volume on a 400GB disk:
:
:$ df -ih .
:Filesystem   Size   Used  Avail Capacity iused ifree %iused  Mounted on
:Backup       371G   314G    57G    85% 2642085     0  100%   /backup

    Interesting.  It should have a full-sized undo area, which means the
    dependancies resulted in 600MB+ worth of undos.  I'll have to start
    testing with hardlinks.

    Be sure to regularly prune and reblock that sucker.  If you aren't
    using the history feature I expect you'll want to mount it 'nohistory'
    too.  I found out the hard way that one still needs to spend about
    5 minutes a day reblocking a HAMMER filesystem to keep fragmentation
    in check.
