Bug#192882: can't reproduce on vfat fs

["Sandro Tosi" <matrixhasu@gmail.com>]

Hello,
I got xfs and mc with these versions:

# mcedit -V
GNU Midnight Commander 4.6.1
# mkfs.xfs -V
mkfs.xfs version 2.9.4
# uname -r
2.6.22-2-amd64

And I've tried to reproduce the bug, with no luck:

zion:/tmp# dd if=/dev/zero of=/tmp/test count=40000

zion:/tmp/testmnt# cat important_file
test string
123
123
123

So, I've tried to pad the file with some stuff generated by this script:

zion:/tmp# python -c 'for i in range(1,1024):  print "%s
0123456789012345678901234567890123456789" % i' | wc -c
45951
zion:/tmp# python -c 'for i in range(1,1024):  print "%s
0123456789012345678901234567890123456789" % i' > /tmp/stuff

The I've included /tmp/stuff into /tmp/testmnt/important_file and
saving, but I recieved "Cannot save file" but the file is saved until
possible:

zion:/tmp/testmnt# ls -l
total 11500
-rw-r--r-- 1 root root 11751424 2008-01-13 19:23 b
-rw-r--r-- 1 root root    24576 2008-01-13 19:49 important_file
zion:/tmp/testmnt# df -k .
Filesystem           1K-blocks      Used Available Use% Mounted on
/tmp/test                11584     11564        20 100% /tmp/testmnt

I hope this can help. If you need additional help/info, just ask.

Regards,
Sandro
