<title>ext3: fix broken handling of EXT3_STATE_NEW</title>

<id>de329820e920cd9cfbc2127cad26a37026260cce</id>
<content type='text'>
In commit 9df93939b735 ("ext3: Use bitops to read/modify
EXT3_I(inode)-&gt;i_state") ext3 changed its internal 'i_state' variable to
use bitops for its state handling.  However, unline the same ext4
change, it didn't actually change the name of the field when it changed
the semantics of it.

As a result, an old use of 'i_state' remained in fs/ext3/ialloc.c that
initialized the field to EXT3_STATE_NEW.  And that does not work
_at_all_ when we're now working with individually named bits rather than
values that get masked.  So the code tried to mark the state to be new,
but in actual fact set the field to EXT3_STATE_JDATA.  Which makes no
sense at all, and screws up all the code that checks whether the inode
was newly allocated.

In particular, it made the xattr code unhappy, and caused various random
behavior, like apparently

	https://bugzilla.redhat.com/show_bug.cgi?id=577911

So fix the initialization, and rename the field to match ext4 so that we
don't have this happen again.

This gives the filesystem more information about the writeback that
is happening.  Trond requested this for the NFS unstable write handling,
and other filesystems might benefit from this too by beeing able to
distinguish between the different callers in more detail.

At several places we modify EXT3_I(inode)-&gt;i_state without holding i_mutex
(ext3_release_file, ext3_bmap, ext3_journalled_writepage, ext3_do_update_inode,
...). These modifications are racy and we can lose updates to i_state. So
convert handling of i_state to use bitops which are atomic.

Get rid of extenddisksize parameter of ext3_get_blocks_handle(). This seems to
be a relict from some old days and setting disksize in this function does not
make much sence. Currently it was set only by ext3_getblk().  Since the
parameter has some effect only if create == 1, it is easy to check that the
three callers which end up calling ext3_getblk() with create == 1 (ext3_append,
ext3_quota_write, ext3_mkdir) do the right thing and set disksize themselves.

In data=writeback mode, start an asynchronous flush when closing a
file which had been previously truncated down to zero.  This lowers
the probability of data loss in the case of applications that attempt
to replace a file using truncate.
