Hi, all

 

It looks like statfs call reports incorrect amount of free space available on device. It is off by the number of "deleted" but "uncollected" by garbage collector files on device which can be signifficant in certain cases.

Such files belongs to "deleted" directory and while the amount of space occupiend by data in such files is acounted as free, the entry in directory is NOT.

 

The proposed fix does two things:

 

1:  nDeletedFiles variable would correctly count the number of "deleted" but uncollected files

2:  the number of free blocks is adjusted by that value.
