Subject: [PATCH 6.18.y 7/8] smb: move some duplicate struct definitions to common/fscc.h
Date: Thu, 5 Nov 2026 12:58:42 -0500 [thread overview]
Message-ID: <20261105175828.2192358-7-sashal@kernel.org> (raw)
In-Reply-To: <20261105175828.2192358-1-sashal@kernel.org>
From: ChenXiaoSong <chenxiaosong@kylinos.cn>
[ Upstream commit d7edd3892d97e6746e30f36f4f13f887ec4d80ed ]
Modify the following places:
- smb2_file_ntwrk_info -> smb2_file_network_open_info
- struct filesystem_device_info -> FILE_SYSTEM_DEVICE_INFO
- struct file_directory_info -> FILE_DIRECTORY_INFO
- struct file_full_directory_info -> FILE_FULL_DIRECTORY_INFO
- struct file_both_directory_info -> FILE_BOTH_DIRECTORY_INFO
- struct file_id_full_dir_info -> FILE_ID_FULL_DIR_INFO
- struct filesystem_posix_info -> FILE_SYSTEM_POSIX_INFO
The fields of these structures are exactly the same on both client and
server, so move duplicate definitions to common header file.
