[lanopk]

Feature request can skip this form. Bug report must complete it. Check List must be 100% match or it will be automatically closed without further discussion. Please remove this line.

Environment

• Windows version: windows 11
• Processor architecture: x64
• Dokany version: 2.0.3.1000
• Library type (Dokany/FUSE): Dokany/DokanDotNet

Check List

• [x] I checked my issue doesn't exist yet
• [ ] My issue is valid with mirror default sample and not specific to my user-mode driver implementation
• [x] I can always reproduce the issue with the provided description below.
• [x] I have updated Dokany to the latest version and have reboot my computer after.
• [ ] I tested one of the last snapshot from appveyor CI

Description

WriteFileEvents are not called in order. If you look at Process Monitor, the explorer is calling WriteFile in order. However, Dokan's WriteFile callback is not called in order. How do I get WriteFile to be called in order?

Logs

Please attach in separate files: mirror output, library logs and kernel logs. In case of BSOD, please attach minidump or dump analyze output.

Looking at the timestamp they seem to all be issued at the same and not sequentially time by explorer. You cannot force them to be sequential and it should not matter.
