[Dazuko-devel] Patch 1/5

[Lino Sanfilippo]

Hi all,

here are some patches against the recent stable dazukofs version (3.1.3).
Hope you find them useful.

Regards,
Lino Sanfilippo


Patch 1:
Implements the gettr() inode operation. This is for filesystems that 
implement
their own operation instead of using the generic one (like xfs).
