Subject: [PATCH v6 0/2] smb: move duplicate definitions to common header file

From: ChenXiaoSong <chenxiaosong@...inos.cn>

In order to maintain the code more easily, move some duplicate definitions
to common header file. Add some MS documentation references for macro and
struct definitions.

I have tested all patches using xfstests and smbtorture, and no additional
test failures were observed in the results. The detailed test results can
be found in https://chenxiaosong.com/en/smb-test/20251113.html

v3: https://lore.kernel.org/all/20251014071917.3004573-1-chenxiaosong.chenxiaosong@linux.dev/
The following patches from v3 have already been merged into the mainline:
  - d877470b5991 smb: move some duplicate definitions to common/cifsglob.h
  - 379510a815cb smb/server: fix possible refcount leak in smb2_sess_setup()
  - 6fced056d2cc smb/server: fix possible memory leak in smb2_read()

v4: https://lore.kernel.org/all/20251027071316.3468472-1-chenxiaosong.chenxiaosong@linux.dev/
v5: https://lore.kernel.org/all/20251102073059.3681026-1-chenxiaosong.chenxiaosong@linux.dev/
The following patches from v4 and v5 have been applied to the ksmbd-for-next-next branch: https://git.samba.org/?p=ksmbd.git;a=shortlog;h=refs/heads/ksmbd-for-next-next

    for a single struct.
  - Patch #0002: make FILE_SYSTEM_ATTRIBUTE_INFO.FileSystemName a flexible array member.
