In case of truncate errors we explicitly remove inode from in-core
orphan list via orphan_del(NULL, inode) without modifying the on-disk list.
But later on, the same inode may be inserted in the orphan list again
which will result the on-disk linked list getting corrupted. If inode
i_dtime contains valid value, then skip on-disk list modification.

ext4_fiemap() rounds the length of the requested range down to
blocksize, which is is not the true number of blocks that cover the

requests only the first byte of a file: not a single extent will be

We fix this by calculating the last block of the region and then
subtract to find the number of blocks in the extents.

This patch fixes three problems in the handling of the
EXT4_IOC_MOVE_EXT ioctl:
1. In current EXT4_IOC_MOVE_EXT, there are read access mode checks for
original and donor files, but they allow the illegal write access to
donor file, since donor file is overwritten by original file data. To
fix this problem, change access mode checks of original (r->r/w) and
donor (r->w) files.
2. Disallow the use of donor files that have a setuid or setgid bits.
3. Call mnt_want_write() and mnt_drop_write() before and after
ext4_move_extents() calling to get write access to a mount.

because EXT4_SB(sb)->s_group_info could be freed in ext4_put_super

At the beginning of ext4_move_extent(), we call
ext4_discard_preallocations() to discard inode PAs of orig and donor
inodes. But in the following case, blocks can be double freed, so
move ext4_discard_preallocations() to the end of ext4_move_extents().
1. Discard inode PAs of orig and donor inodes with
ext4_discard_preallocations() in ext4_move_extents().
orig : [ DATA1 ]
donor: [ DATA2 ]
2. While data blocks are exchanging between orig and donor inodes, new
inode PAs is created to orig by other process's block allocation.
(Since there are semaphore gaps in ext4_move_extents().) And new
inode PAs is used partially (2-1).
2-1 Create new inode PAs to orig inode
orig : [ DATA1 | used PA1 | free PA1 ]
donor: [ DATA2 ]
3. Donor inode which has old orig inode's blocks is deleted after
EXT4_IOC_MOVE_EXT finished (3-1, 3-2). So the block bitmap
corresponds to old orig inode's blocks are freed.
3-1 After EXT4_IOC_MOVE_EXT finished
orig : [ DATA2 | free PA1 ]
donor: [ DATA1 | used PA1 ]
3-2 Delete donor inode
orig : [ DATA2 | free PA1 ]
donor: [ FREE SPACE(DATA1) | FREE SPACE(used PA1) ]
4. The double-free of blocks is occurred, when close() is called to
orig inode. Because ext4_discard_preallocations() for orig inode
frees used PA1 and free PA1, though used PA1 is already freed in 3.
4-1 Double-free of blocks is occurred
orig : [ DATA2 | FREE SPACE(free PA1) ]

ext4_move_extents() checks the logical block contiguousness
of original file with ext4_find_extent() and mext_next_extent().
Therefore the extent which ext4_ext_path structure indicates
must not be changed between above functions.
But in current implementation, there is no i_data_sem protection
between ext4_ext_find_extent() and mext_next_extent(). So the extent
which ext4_ext_path structure indicates may be overwritten by
delalloc. As a result, ext4_move_extents() will exchange wrong blocks
between original and donor files. I change the place where
acquire/release i_data_sem to solve this problem.
Moreover, I changed move_extent_per_page() to start transaction first,
and then acquire i_data_sem. Without this change, there is a
possibility of the deadlock between mmap() and ext4_move_extents():
* NOTE: "A", "B" and "C" mean different processes
A-1: ext4_ext_move_extents() acquires i_data_sem of two inodes.
B: do_page_fault() starts the transaction (T),
and then tries to acquire i_data_sem.
But process "A" is already holding it, so it is kept waiting.
C: While "A" and "B" running, kjournald2 tries to commit transaction (T)
but it is under updating, so kjournald2 waits for it.
A-2: Call ext4_journal_start with holding i_data_sem,
but transaction (T) is locked.

Previously add_dirent_to_buf() did not free its passed-in buffer head
in the case of ENOSPC, since in some cases the caller still needed it.
However, this led to potential buffer head leaks since not all callers
dealt with this correctly. Fix this by making simplifying the freeing
convention; now add_dirent_to_buf() *never* frees the passed-in buffer
head, and leaves that to the responsibility of its caller. This makes
things cleaner and easier to prove that the code is neither leaking

To prepare for a direct I/O write, we need to split the unwritten
extents before submitting the I/O. When no extents needed to be
split, ext4_split_unwritten_extents() was incorrectly returning 0
instead of the size of uninitialized extents. This bug caused the
wrong return value sent back to VFS code when it gets called from
async IO path, leading to an unnecessary fall back to buffered IO.
This bug also hid the fact that the check to see whether or not a
split would be necessary was incorrect; we can only skip splitting the
extent if the write completely covers the uninitialized extent.

After a direct I/O request covering an uninitalized extent (i.e.,
created using the fallocate system call) or a hole in a file, ext4
will convert the uninitialized extent so it is marked as initialized
by calling ext4_convert_unwritten_extents(). This function returns
zero on success.
This return value was getting returned by ext4_direct_IO(); however
the file system's direct_IO function is supposed to return the number
