[PATCHv2 0/5] ext4/jbd2: inline_data fixes and minor cleanups

[Ritesh Harjani]

Hello,

Please find v2 of the inline_data fixes and some minor cleanups found during
code review.

I have dropped patch-6 in v2 which was removing use of t_handle_lock (spinlock)
from within jbd2_journal_wait_updates(). Based on Jan comments, I feel we can
push that as killing of t_handle_lock into a separate series (which will be on
top of this).

v1 -> v2
========
1. Added Jan's Reviewed-by tag & addressed one of his comment on no need to make
jbd2_journal_wait_updates() function inline.
2. Dropped patch-6 as described above.

Description
============
Patch[1]: fixes BUG_ON with inline_data which was reported [1] with generic/475.

Patch[2]: is mostly cleanup found during code review of inline_data code.

Patch[3]: is a possible memory corruption fix in case of krealloc failure.

Patch[4-5]: Cleanups.

[v1]: https://lore.kernel.org/linux-ext4/cover.1642044249.git.riteshh@xxxxxxxxxxxxx/T/
