Re: Re [2]: [PATCH] Mark CONFIG_UFS_FS_WRITE as BROKEN

[Alexey Dobriyan <adobriyan@gmail.com>]

Thanks, these two patches makes things better but not much better.

1.

        inode->i_blocks = sb->s_blocksize / UFS_SECTOR_SIZE;
+       inode->i_size = sb->s_blocksize;
        de = (struct ufs_dir_entry *) dir_block->b_data;

This creates directories which are 2048 bytes in size. Native ones are
512 bytes.

	inode->i_size = 512;

makes mkdir and rm reliable for me both on linux and OpenBSD.

2. Second patch indeed makes hangs disaapear. However, data corruption
   is still in place:

Try

	for i in $(seq 1 10000); do echo $i; done >10000-linux.txt
	cp 10000-linux.txt >/mnt/openbsd/10000-openbsd.txt

Now corruption structure is following:

There are all zeros in 0800-4000 and 4800-8000 range. 0000-3800 from
original file is dropped (that 9 it's from 3089).
