Subject: [PATCH 00/10] smb: improve search speed of SMB2 maperror
Date: Thu, 4 Dec 2025 12:58:08 +0800 [thread overview]
Message-ID: <20251204045818.2590727-1-chenxiaosong.chenxiaosong@linux.dev> (raw)
From: ChenXiaoSong <chenxiaosong@kylinos.cn>
Before applying this patchset, when searching for the last element of
smb2_error_map_table array and calling smb2_print_status(),
3480 comparisons are needed.
After applying this patchset, only 10 comparisons are required.
ChenXiaoSong (10):
smb/client: reduce loop count in map_smb2_to_linux_error() by half
smb/client: remove unused elements from smb2_error_map_table array
smb: add two elements to smb2_error_map_table array
smb/client: sort smb2_error_map_table array
smb/client: use bsearch() to find target status code
smb/client: introduce smb2_get_err_map()
smb/client: introduce smb2maperror KUnit tests
smb/server: rename include guard in smb_common.h
smb: create common/common.h and common/common.c
smb: move client/smb2maperror.c to common/
