One of the changesets posted by Linus on August 2 introduced
a bug in the FAT fs:
Even when a fat32 fs is mounted read-write I now get error
messages claiming the fs is 'read-only' when I try to write
to it.
The only change I can see which fits the timing is to inode.c
which was posted on August 2. Apologies if I am blaming
the wrong changeset.
Could someone confirm this bug for me?
Thanks!

Okay, I've now found the comments about specifying values
for iocharset and codepage, and read-write works again.
However, IMHO the 'mount' command should simply refuse to
mount a FATfs read/write unless iocharset and codepage are
specified. As things stand now, 'mount' reports the fs is
mounted rw when it simply is not true.

This is intention.
The default codepage/iocharset which is easy to cause a mistake and
unclear was deleted from fatfs. So default is mounted as read only.
You need to explicitly specify the "codepage" and "iocharset" options.

To minimise confusion, is it an idea that NTFS and FAT use the same
mount options? Right now NTFS uses "nls" and VFAT "iocharset".

"nls" option is used by only NTFS. Other filesystems is using "iocharset".
Umm.. Why was "iocharset" option deprecated?
