[Cluster-devel] [PATCH 00/12] gfs2: punch hole

[Bob Peterson <rpeterso@redhat.com>]

----- Original Message -----
| These patches fix a few minor issues in the non-recursive delete
| implementation, add upper bound parameters so that these functions can
| be used for punching holes in addition to truncating files at a given
| position, and implement the fallocate hole punching operation base don
| that.
| 
| These patches pass xfstests, but they haven't been tested very heavily
| beyond that.

Hi,

Thanks. I pushed the (now-revised) punch-hole patch set to the for-next
branch of linux-gfs2 repository. I also threw a bunch of my truncate
and delete tests at them, and it all seemed to work properly.
