I have discussed this patch with Nickolay Semenov before he has posted 
it to bug tracker.

Note that this patch extends the filesystem API in some way. It allow 
filesystem implementation to report that 
rtems_filesystem_evaluate_parent() did not support parent directory 
evaluation by file name by returning the ENOTSUPP error code. In this 
case, directory write permission checks will be ignored. (It has no too 
much sense for FAT file system, and, anyway it is better than disallow 
file deletion). I'm not sure, it may be reasonable to document this API 
change.
