Hi,
Something weird is going on with VFS return codes with kernel
2.4.0-test10-pre3:
[root@sturm glibc-2.1.92]# df /var/tmp
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/hda3 127383 127383 0 100% /var
[root@sturm glibc-2.1.92]# df -i /var/tmp
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/hda3 32912 2936 29976 9% /var
[root@sturm glibc-2.1.92]# mkdir /var/tmp/tst
mkdir: cannot create directory `/var/tmp/tst': Input/output error
[root@sturm glibc-2.1.92]#
Just a guess, but I think this is caused by:
dir_block = ext2_bread (inode, 0, 1, &err);
if (!dir_block) {
inode->i_nlink--; /* is this nlink == 0? */
mark_inode_dirty(inode);
iput (inode);
return -EIO;
}
in fs/ext2/namei.c:ext2_mkdir(). Note that I can't find any cases where
ext2_alloc_block() would actually give a ENOSPC return.
Note (again) the dodgy return error by reference, and then we totally
ignore 'err', so even if ext2_alloc_block() was fixed, it wouldn't
matter unless this and probably other places were also fixed to return
err instead of EIO.
