Hi Mark/Joel, I meet with some meta allocation bugs when I implement reflink these days. And after some investigation, I think we should have the same problem when we have PAGE_SIZE > CLUSTER_SIZE. So I create a scenario today in one ppc box and try. the box panic as I expected. ;) The scenario is that: Create a file with the disk layout like this(with bs=512, and cs=4K). debugfs: stat

Hi, OpenSSH 7.6p1 is almost ready for release, so we would appreciate testing on as many platforms and systems as possible. This is a bugfix release. Snapshot releases for portable OpenSSH are available from http://www.mindrot.org/openssh_snap/ The OpenBSD version is available in CVS HEAD: http://www.openbsd.org/anoncvs.html Portable OpenSSH is also available via git using the instructions at

Hi all, So I have finally finished the v1 of reflink for ocfs2. It has some bugs that I am still investigating, but the schema is almost there. So I'd like to send it out first for review. And Tristan and I will continue to work on the stability of the code. The general information for reflink, please see http://oss.oracle.com/osswiki/OCFS2/DesignDocs/Reflink. For the design doc, please

Hi all, Change from v1 to v2: bug fix and metadata/credits reservation improvement. The general information for reflink, please see http://oss.oracle.com/osswiki/OCFS2/DesignDocs/Reflink.

The following series of patches attempts to detach metadata I/O from struct inode. They are currently tied together pretty tightly. Metadata reads happen via the ocfs2_read_blocks() functions, writes via both jbd2 and ocfs2_write_blocks(). - Each inode has a cache of associated metadata blocks stored on its ip_metadata_cache member. The ocfs2_read/write_blocks() functions take a struct

The following patches implement indexed directory support in Ocfs2, mostly according to the design doc I wrote up a while ago: http://oss.oracle.com/osswiki/OCFS2/DesignDocs/IndexedDirectories The patches have been rebased on top of 2.6.29-rc2. It should be trivial to put them into merge_window. Things are what I'd call complete now. I'd like to get these into the merge_window branch

What it is: vhost net is a character device that can be used to reduce the number of system calls involved in virtio networking. Existing virtio net code is used in the guest without modification. There's similarity with vringfd, with some differences and reduced scope - uses eventfd for signalling - structures can be moved around in memory at any time (good for migration, bug work-arounds

Hi, The following patches comprise the bulk of Ocfs2 updates for the 2.6.30 merge window. Aside from larger, more involved fixes, we're adding the following features, which I will describe in the order their patches are mailed. Sunil's exported some more state to our debugfs files, and consolidated some other aspects of our debugfs infrastructure. This will further aid us in debugging
