Subject[PATCH v3 2/5] fat: allocate persistent inode numbers
Date
From: Namjae Jeon <namjae.jeon@samsung.com>

All the files on a FAT partition have an on-disk directory entry.
The location of these entries, i_pos, is unique and is constructed by
the fat_make_i_pos() function.We can use this as the inode number making
it persistent across remounts.
