Subject: [PATCH v4 00/10] smb: improve search speed of SMB2 maperror
Date: Sat, 6 Dec 2025 23:18:16 +0800 [thread overview]
Message-ID: <20251206151826.2932970-1-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(),
3486 comparisons are needed.
After applying this patchset, only 10 comparisons are required.
v1: https://lore.kernel.org/linux-cifs/20251204045818.2590727-1-chenxiaosong.chenxiaosong@linux.dev/
The three patches from v1 have already been applied to the for-next branch of cifs-2.6.git.
Please replace the following patches:
- [v1 01/10] smb/client: reduce loop count in map_smb2_to_linux_error() by half: https://git.samba.org/sfrench/?p=sfrench/cifs-2.6.git;a=commitdiff;h=26866d690bd180e1860548c43e70fdefe50638ff
- Replace it with this version(v4) patch #0001: update commit message: array has 1743 elements
- [v1 02/10] smb/client: remove unused elements from smb2_error_map_table array: https://git.samba.org/sfrench/?p=sfrench/cifs-2.6.git;a=commitdiff;h=905d8999d67dcbe4ce12ef87996e4440e068196d
- It is the same as patch #0002 in this version(v4).
- [v1 03/10] smb: add two elements to smb2_error_map_table array: https://git.samba.org/sfrench/?p=sfrench/cifs-2.6.git;a=commitdiff;h=ba521f56912f6ff5121e54c17c855298f947c9ea
- Replace it with this version(v4) patch #0003 #0004.
v3: https://lore.kernel.org/linux-cifs/20251205132536.2703110-1-chenxiaosong.chenxiaosong@linux.dev/
v3->v4:
- Patch #0008: the KUnit test searches all elements of the smb2_error_map_table array
- Create patch #0009
