Hello, All !

I got very interesting bug for msdos fs. The problem starting ( and
is reproductable ) when doing umount/mount dos fs. Seems that problem in
cache rather than in fs code.

[root@unicorn]/dos1# ls -gFl

no program could read any file in any directory, except :
when I remount with o=rw, i can write to dos fs and this files are readable.
More than that - all files with the same extension are readable, but they
got equal size. And I can't create file with any extension...
Seems, that dos extensions are wiped out !

[root@unicorn]/dos1/temp# echo >fil1
[root@unicorn]/dos1/temp# ls -la fil1
-rw-r--r-- 1 root root 1 Aug 4 02:58 fil1
[root@unicorn]/dos1/temp# echo "1111">fil1.1
[root@unicorn]/dos1/temp# ls -la fil1*
-rw-r--r-- 1 root root 5 Aug 4 02:59 fil1
[root@unicorn]/dos1/temp#

Bye.
