Subject: [Qemu-devel] [PATCH 0/7] block: Preallocated truncation for gluster and sheepdog
Date: Tue, 13 Feb 2018 14:03:49 +0100 [thread overview]
Message-ID: <20180213130356.8885-1-mreitz@redhat.com> (raw)
As far as I can see, these are the only protocols beside file-posix that
support preallocated creation. In contrast to file-posix, however, they
have not supported preallocated truncation so far. This series brings
their truncation code to feature parity with their creation code in this
regard.
Note that I do not have a test setup for either of the two drivers, so I
do not actually know whether this works. Anyone with a setup is more
than welcome to test this series.
Max Reitz (7):
gluster: Move glfs_close() to create's clean-up
gluster: Pull truncation from qemu_gluster_create
gluster: Query current size in do_truncate()
gluster: Add preallocated truncation
sheepdog: Make sd_prealloc() take a BDS
sheepdog: Pass old and new size to sd_prealloc()
sheepdog: Allow fully preallocated truncation
