They're also incomplete. The openSUSE kernel also needs: http://kernel.suse.com/cgit/kernel-source/tree/patches.suse/btrfs-fs-super.c-add-new-super-block-devices-super_block_d.patch?h=SLE12-SP2 http://kernel.suse.com/cgit/kernel-source/tree/patches.suse/btrfs-btrfs-use-the-new-VFS-super_block_dev.patch?h=SLE12-SP2 ... for ustat() to work properly. I've just forward ported those to the master kernel and am testing now. The /proc/mountinfo thing isn't fixed with these patches either since subvolumes report different device numbers and we don't represent subvolumes as mounts. That's what the patches that I had started writing up a while ago do, but it's still very early for those. -Jeff >> >> On Thu, Feb 16, 2017 at 12:05 PM, Ilan Schwarts <ila...@gmail.com >> <mailto:ila...@gmail.com>> wrote: >> >> Hi, >> >> I hope its ok im reaching to you via mail.. >> I read your message at: >> _https://marc.info/?l=linux-btrfs&m=148701370108477&w=2 >> <https://marc.info/?l=linux-btrfs&m=148701370108477&w=2>_ >> >> I have the same issue in my kernel driver, Did you find an answer ? >> >> Thanks >> - >> Ilan Schwarts >> >> >> >> >> -- >> >> >> - >> Ilan Schwarts > > -- Jeff Mahoney SUSE Labs
