Bug ID: 55365
           Summary: ntdll:file - test_file_full_size_information()
                    sometimes gets a bad AvailableAllocationUnits value on
                    Windows and Wine
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: [e-mail]
          Reporter: [e-mail]

ntdll:file - test_file_full_size_information() sometimes gets a bad
AvailableAllocationUnits value on Windows and Wine:

file.c:1320: Test failed: [ffsi] CallerAvailableAllocationUnits error
fsi:0x12dbfb5, ffsi: 0x12dbfb6

See https://test.winehq.org/data/patterns.html#ntdll:file

This is very rare as there are only 3 known instances:
* 2023-03-27 linux_gitlab-debian-32
* 2023-06-23 linux_gitlab-debian-32
* 2023-07-27 win21H2_gitlab-win10-21h2-64

This looks very much like a race condition with some other process allocating
or freeing disk space in between the FileFsFullSizeInformation and
FileFsSizeInformation calls. So this is something that should be fixable with
the tryok() API.
