[PATCH v3 0/9] smb/client: fix mode 0 fallocate handling

[Huiwen He <huiwen.he@linux.dev>]

From: Huiwen He <hehuiwen@kylinos.cn>

Changes in v3:

- Move the v2 patch 6 to patch 9, so AllocationSize verification runs after
  the zero-write emulation fixes.
- Extend the v2 patch 9 and move it to patch 8.  It now also handles small
  mode 0 fallocate ranges past EOF, preserving the intervening hole for the
  generic/213 case.
- Update the related commit messages and test notes.

Thanks,
Huiwen He
