Already merged a few hours ago as commit c05d51c773fb.

But you may have fallen afoul of the "either lkml or lore is sick"
issue, so pr-tracker-bot isn't working.

We've had a few of those lately.

Especially with the tree-log.c changes being fairly big, I took a look, and
I have to say that I appreciate (a) the warning in the pull request and (b)
the extensive log messages explaining the problems these patches fix.

I obviously still prefer to see only small and simple one-liners just

do appreciate good explanations.

All my previous pull requests were like that. I did the split branch/tag
beacuse the ambiguous name for branch and brings some hassle to push or
remove them. I thought a separate tag with same top commit as the branch
plus mentioning the tag in the mail would be enough to verify the pulled
branch. But apparently was not, sorry for the trouble.

Oh, please actually ask me to pull the signed tag (exact same
pull-request, just point git request-pull at the tag), because now
what happened was that first I just pulled that branch you mentioned,
and only noticed that "With signed tag:" notice after I had already

Anyway, I redid the pull with the proper signed tag, but it was just

If you have them basically ready, add them to this, I haven't pulled
yet. So I'll just ignore this and wait for another pull request.

Update on this, we've tracked down the crc errors and are doing final
checks on the patches.  Linus are you planning on taking this pull?  If
not I can just fold the new stuff into a bigger request.

Hi,

Any chance to get these in this round?  I think they're good fixes,
a memory leak and a warning fix, both are got from xfstests.

- Btrfs: use right range to find checksum for compressed extents
  https://patchwork.kernel.org/patch/1937031/
- Btrfs: fix memory leak on extent map after fsync
  https://patchwork.kernel.org/patch/1946561/

thanks,

Re: [GIT PULL] Btrfs fixes

 Hi Linus,
 
 My for-linus branch has our batch of btrfs fixes:
 
 git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus
 
 We've been hammering away at a crc corruption as well, which I was
 really hoping to get into this pull.  It isn't nailed down yet, but we
 were finally able to get a solid way to reproduce.  The only good
 news is it isn't a recent regression.
 
 The most important batch of fixes in here come from Ilya.  They address
 a regression Liu Bo found in the balance ioctls for pausing and resuming
 a running balance across drives.
 
 Josef's orphan truncate patch fixes an obscure corruption we'd see
 during xfstests.
 
 Arne's patches address problems with subvolume quotas.  If the user
 destroys quota groups incorrectly the FS will refuse to mount.
 
 The rest are smaller fixes and plugs for memory leaks.

Hi,

Any chance to get these in this round?  I think they're good fixes,
a memory leak and a warning fix, both are got from xfstests.

- Btrfs: use right range to find checksum for compressed extents
  https://patchwork.kernel.org/patch/1937031/
- Btrfs: fix memory leak on extent map after fsync
  https://patchwork.kernel.org/patch/1946561/

thanks,
liubo

I'll get these tested in the next pull.
