NTFS: Fix compilation warnings with gcc-4.0.2 on SUSE 10.0.

	  EOPNOTSUPP is returned.

	- $EA attributes can be both resident and non-resident.

	- Use %z for size_t to fix compilation warnings.  (Andrew Morton)

	- Fix compilation warnings with gcc-4.0.2 on SUSE 10.0.

2.1.24 - Lots of bug fixes and support more clean journal states.

 * Extend the initialized size of an attribute described by the ntfs inode @ni

 * to @new_init_size bytes.  This involves zeroing any non-sparse space between

 * the old initialized size and @new_init_size both in the page cache and on

 * disk (if relevant complete pages are zeroed in the page cache then these may

 * simply be marked dirty for later writeout).  There is one caveat and that is

 * that if any uptodate page cache pages between the old initialized size and

 * the smaller of @new_init_size and the file size (vfs inode->i_size) are in

 * memory, these need to be marked dirty without being zeroed since they could

 * be non-zero due to mmap() based writes.

 * disk (if relevant complete pages are already uptodate in the page cache then

 * these are simply marked dirty).

 *

 * As a side-effect, the file size (vfs inode->i_size) may be incremented as,

 * in the resident attribute case, it is tied to the initialized size and, in

 * with new data via mmap() based writes, so we cannot just zero it.  And since

 * POSIX specifies that the behaviour of resizing a file whilst it is mmap()ped

 * is unspecified, we choose not to do zeroing and thus we do not need to touch

 * the page at all.  For a more detailed explanation see ntfs_truncate() which

 * is in fs/ntfs/inode.c.

 * the page at all.  For a more detailed explanation see ntfs_truncate() in

 * fs/ntfs/inode.c.

 * @cached_page and @lru_pvec are just optimisations for dealing with multiple

 * @cached_page and @lru_pvec are just optimizations for dealing with multiple

 * pages.

 *

 * Return 0 on success and -errno on error.  In the case that an error is

 * this is the case, the necessary zeroing will also have happened and that all

 * metadata is self-consistent.

 *

 * Locking: This function locks the mft record of the base ntfs inode and

 * maintains the lock throughout execution of the function.  This is required

 * so that the initialized size of the attribute can be modified safely.

 * Locking: i_sem on the vfs inode corrseponsind to the ntfs inode @ni must be

 *	    held by the caller.
