Hi. I've rebased the rmap+reflink patches against 4.6-rc1. There are also some patches to start the process of drafting a metadata scrubber for XFS and/or to give us more to talk about at LSF. The thirty or so bugfixes tacked on the end of the last patch series seems to be stable enough that I integrated them into the main body of the patches, partly to reduce the number of patches to review and partly to avoid the situation where reviewers complain about something in a patch only to discover that it's fixed by a later patch that reorganizes everything. The first fifteen patches from Dave's latest posting of rmapbt code are integrated here too. I've not gotten to the last two, primarily because I need to add rmapbt and refcountbt update intents and want to use the interval query code for rmap updates. This will be its own sprint, starting just after I send this email. This leaves us basically in the same place as we were at the end of the 4.5 cycle, but rebased against 4.6. One exception is that the "rmapxbt" is gone; now there's only one rmapbt format regardless of whether reflink is enabled. As far as xfsprogs goes, I imported (I think) all the libxfs updates from 4.6-rc1, and broke out the huge horrible libxfs changes into individual patches that are direct descendants of the kernel-side patches. They have the same subject line + commit message, so as to make it easier to cross-reference trees and to port changes from one to another. This also brings the xfsprogs libxfs updates for rmap and reflink up to date with the stuff that has been hanging out in the kernel. Unfortunately that means there are now ~105 patches there. There are also a bunch of xfstests updates that fix various test errors and add more tests to check out recovery of extents being held for CoW operations that didn't succeed before crashing; and ensure that we can't have reflinked swap files. There are also minor documentation and manpage updates. Anyway, the development trees are now posted to github under "djwong-devel" branches: https://github.com/djwong/linux/commits/djwong-devel https://github.com/djwong/xfsprogs/commits/djwong-devel https://github.com/djwong/xfstests/commits/djwong-devel https://github.com/djwong/xfs-documentation/commits/djwong-devel https://github.com/djwong/man-pages/commits/djwong-devel I'll patchbomb the mailing list when I finish the next XFS sprint or before LSF, whichever comes first. Christoph: Does that problem you observed with NFS blocking for a long time when someone uses fallocate to unshare a lot of shared blocks? The last patch in the kernel series disables the dirty page flush, and I'm curious to see if it helps any. (I'd conservatively assumed that a preemptive CoW had to fsync as well, but let's evaluate if skipping it is worth the risk.) --D On Fri, Mar 04, 2016 at 05:15:30PM -0800, Darrick J.
