[PATCH v3 00/15] NTB: ntb_transport: Miscellaneous fixes

[Koichiro Den]

Hi,

This series attempts to fix miscellaneous issues in ntb_transport. Some
of these were split from the direct TX/RX series v1 [1], as they stand
on their own. Based on v7.3-rc2.

Dave, Frank and Logan, for v3, patches 3 and 6 don't yet have
Reviewed-by tags. Could you take a look?

Best regards,
Koichiro

Changes in v3:
  - Convert flags to atomic_t in a new prep patch. (Frank)
  - Drop the redundant TX credit assertion. (Sashiko)
  - Collect Reviewed-by tags. Thanks to Frank, Logan and Dave.

Changes in v2:
  - Address Sashiko feedback, including regressions introduced by v1,
    with new patches 5 and 10.
    Note that to keep the series manageable, this revision does not
    attempt to fix all the reported pre-existing issues.
  - Add a fix for client removal ordering (patch 14).
  - Reorder patches, moving v1 patch 4 after the fixes it depends on.
  - Add missing Cc: stable@xxxxxxxxxxxxxxx.

v2: https://lore.kernel.org/r/20260910040836.3792333-1-den@xxxxxxxxxxxxx/
v1: https://lore.kernel.org/r/20260907142429.951930-1-den@xxxxxxxxxxxxx/
