[PATCH 0/3] fs/fat: fix handling of full disk

[Heinrich Schuchardt]

Currently we have two functions with redundant coding to find an empty
cluster:

* find_empty_cluster() seeks from the beginning of the FAT table
* determine_fatent() seeks after a given entry

Both do not detect the end of the FAT table correctly and return an invalid
cluster number if no empty entry if found.

Correctly determine empty FAT entries and full disk correctly.

Carve out a function for creating directory entries to avoid code
duplication.

Heinrich Schuchardt (3):
  fs: fat: finding an empty FAT cluster
  fs: fat: determine_fatent() error handling
  fs: fat: carve out fat_create_dir_entry()
