Summary: DeleteFile() gives Error 87 for file created by mknod
                    -m 644 msr c 202 0
           Product: Wine
           Version: 1.1.29
          Platform: PC
               URL: http://rh-software.com/
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: kernel32

Test Program Source, Binary and run log

SIV (http://rh-software.com/) needs to access MSRs which it now does by
creating the /dev/cpu/0/msr devices using the mknod command, this works well
'till it tries to detele them when it gets an error 87  Invalid parameter
return code.  I have created the attached program to show this bug in
DeleteFile().  I have tried to get round this by doing the CreateFile() myself.
I have tried to find why this is failing, it seems to be in service/file.c
within the routine static struct object *create_file().

DeleteFile() is a Win32 API and has nothing to do with Linux devices.

I also ment to state that I can hapilly open, position and read these devices
with CreateFile()/SetFilePointer()/ReadFile(), it's only when
FILE_FLAG_DELETE_ON_CLOSE is specified there is a problem with CreateFile()
which is probably why DeleteFile() fails.

Tried the test program at my machine:

$ sudo rm -r /dev/cpu
$ sudo su
# wine noo.exe
NOO - Delete failure of file created by /bin/mknod -m 644 msr c 202 0
NOO - Delete msr Success, Return   Error Code 0   Success
crw-r--r-- 1 root root 202, 0 2009-09-18 00:55 msr
NOO - Delete msr Failure, Return   Error Code 87  Invalid parameter
NOO - done
# exit
$ ls -l /dev/cpu/0/msr 
crw-rw---- 1 root root 202, 0 2009-09-18 00:55 /dev/cpu/0/msr
$ wine --version
wine-1.1.29-83-gdad99e2

Hence, I confirm.

That's on purpose, DeleteFile doesn't delete devices on Windows either.
