Subject: [PATCH v1 0/3] smb: client: fix file compression flag ioctls
Date: Sat, 6 Jun 2026 22:43:13 +0800 [thread overview]
Message-ID: <20260606144316.183032-1-huiwen.he@linux.dev> (raw)
From: Huiwen He <hehuiwen@kylinos.cn>
This series fixes three CIFS compression flag ioctl issues.
Patch 1 fixes lsattr showing random flags when the file does not
have the compressed attribute set.
Patch 2 fixes chattr +c failures caused by sending
FSCTL_SET_COMPRESSION on a handle without FILE_WRITE_DATA access.
Patch 3 fixes chattr -c failures by sending
COMPRESSION_FORMAT_NONE when FS_COMPR_FL is cleared.
Thanks,
Huiwen He
