Subject: [PATCH v2 0/9] smb/client: fix mode 0 fallocate handling
Date: Wed, 24 Jun 2026 10:15:41 +0800	[thread overview]
Message-ID: <20260624021550.1548952-1-huiwen.he@linux.dev> (raw)

From: Huiwen He <hehuiwen@kylinos.cn>

Changes since v1:
- Add patch 2 to preserve FSCTL_SET_SPARSE errors and only cache
  EOPNOTSUPP as missing sparse support.
- Update patch 6 to allow verified EOF-adjacent fallocate on non-sparse
  files.
- Add patch 7 to handle allocated ranges that overlap the requested
  fallocate range.
- Update patch 9 to limit zero-write emulation to small EOF-adjacent
  ranges on sparse files.
