I can indeed confirm that this fixes the stall. This however does not

There is a race between a task aborting a transaction during a commit,
a task doing an fsync and the transaction kthread, which leads to an
use-after-free of the log root tree. When this happens, it results in a
stack trace like the following:

When adding the comments for subpage metadata code, I inserted the
comment patch into the wrong position, and then use that patch as a
separator between data and metadata write path.
Thus the submitted metadata write path patchset lacks the real functions
to submit subpage metadata write bio.

The new function, end_bio_subpage_eb_writepage(), will handle the
metadata writeback endio.
The major differences involved are:
- How to grab extent buffer
Now page::private is a pointer to btrfs_subpage, we can no longer grab
extent buffer directly.
Thus we need to use the bv_offset to loca
The new function, write_one_subpage_eb(), as a subroutine for subpage
metadata write, will handle the extent buffer bio submission.
The major differences between the new write_one_subpage_eb() and
write_one_eb() is:
- No page locking
When entering write_one_subpage_eb() the page is no longer loc
For subpage metadata, we don't use page locking at all.
So just skip the page locking part for subpage.
All the remaining routine can be reused.

The major difference between submit_eb_page() and submit_eb_subpage()

Now we use find_extent_buffer_nospinlock() other than using
