Subject[PATCH v6 0/3] fs: fat: add ioctl to modify fat filesystem partion volume label
Date
The FAT filesystem partition volume label can be read with
FAT_IOCTL_GET_VOLUME_LABEL and written with FAT_IOCTL_SET_VOLUME_LABEL.

FAT volume label (volume name) is exactly same stored in boot sector and root
directory. Thus, the boot sector just needs to be upgrade when the label
writing.

v6:
1. fixed volume label name check function.
2. add volume label entry if no volume label.
v5:
1. find the volume label entry through the scan function.
2. the volume label only retains the d-characters (reference from Ecma-107).
v4:
1. read/write volume label from/to the location of the respective version.
2. correct volume label check reference from mkfs.fat.
3. fixed some code issue.
v3:
1. write volume label both boot sector and root directory.
v2:
1. add filesystem version check.
2. add diretory permissions check.
3. add volume label string check.
4. fixed part of return value.
5. fixed some indent issue.
6. remove sync_dirty_buffer().
