This is mainly to fix problems exposed by Chandan's fix for 64K nodesize.
Thanks for the fix. That's a lot of new code that I don't feel
comfortable to put to the upcomming release, so I'll merge 1 and 6 now
and queue the rest for 4.9.1.
Feel free to delay them to 4.9.1.
But since we have regression, I think we'd better delay the following
patches along with the rollback rework:
btrfs-progs: convert: Fix migrate_super_block() to work with 64k sectorsize
btrfs-progs: convert: Prevent accounting blocks beyond end of device
And the 6th patch of the patchset.
The 2 convert fixes are completely fine, but they slightly change the
chunk layout, and makes 4K sectorsize convert test fails.
So is the 6th patch, which enhanced the testcases, to make them always
fail if rollback rework is not applied.
So IMHO it's better to ensure the v4.9 release can pass self tests.
(Even we know it has bugs)
And fixes all the known convert bugs in v4.9.1.
How do you think about this idea?
Thanks,
Qu
