For dio read, bio will be leave in flight when a successful partial
aio read have been setup, blockdev_direct_IO() will return
-EIOCBQUEUED. In the case, iter->iov_offset will be not advanced,
the oops reported by syzbot will occur if revert iter->iov_offset
with iov_iter_revert(). The unwritten part had been zeroed by aio
read, so there is no need to zero it in dio read.

Since the read operation beyond the ValidDataLength returns zero,
if we just extend the size of the file, we don't need to zero the
extended part, but only change the DataLength without changing
the ValidDataLength.

An uninitialized time is set to ctime/atime in __exfat_write_inode().
It causes xfstests generic/003 and generic/192 to fail.
And since there will be a time gap between setting ctime/atime to
the inode and writing back the inode, so ctime/atime should not be
set again when writing back the inode.

Patch series "start removing writepage instances v2".
The VM doesn't need or want ->writepage for writeback and is fine with
just having ->writepages as long as ->migrate_folio is implemented.
This series removes all ->writepage instances that use
block_write_full_page directly and also have a plain mpage_writepages
based ->writepages.
This patch (of 7):
->writepage is a very inefficient method to write back data, and only used
through write_cache_pages or a a fallback when no ->migrate_folio method
is present.
Set ->migrate_folio to the generic buffer_head based helper, and remove
the ->writepage implementation.

The prandom_u32() function has been a deprecated inline wrapper around
get_random_u32() for several releases now, and compiles down to the
exact same code. Replace the deprecated wrapper with a direct call to
the real function. The same also applies to get_random_int(), which is
just a wrapper around get_random_u32(). This was done as a basic find
and replace.

Since the timestamps need to be updated, the directory entries
will be updated by mark_inode_dirty() whether or not a new

In exfat_truncate(), the computation of inode->i_blocks is wrong if
the file is larger than 4 GiB because a 32-bit variable is used as a
mask. This is fixed and simplified by using round_up().
Also fix the same buggy computation in exfat_read_root() and another
(correct) one in exfat_fill_inode(). The latter was fixed another way
last month but can be simplified by using round_up() as well. See:

MediaFailure and VolumeDirty should be retained if these are set before

In '3.1.13.3 Media Failure Field' of exfat specification describe:
If, upon mounting a volume, the value of this field is 1,
implementations which scan the entire volume for media failures and
record all failures as "bad" clusters in the FAT (or otherwise resolve
media failures) may clear the value of this field to 0.
Therefore, We should not clear MediaFailure without scanning volume.
In '8.1 Recommended Write Ordering' of exfat specification describe:
Clear the value of the VolumeDirty field to 0, if its value prior to

Therefore, We should not clear VolumeDirty after mounting.
