5994e8b643 fs: Create a common fs_devread for ext4/reiserfs/zfs
The ext4, reiserfs and zfs filesystems all have their own implementation
of the same function, *_devread. Generalize this function into fs_devread
and put the code into fs/fs_internal.c.

4101f68792 dm: Drop the block_dev_desc_t typedef
Use 'struct' instead of a typdef. Also since 'struct block_dev_desc' is long
and causes 80-column violations, rename it to struct blk_desc.

7c4213f6a5 block: pass block dev not num to read/write/erase()
This will allow the implementation to make use of data in the block_dev
structure beyond the base device number. This will be useful so that eMMC
block devices can encompass the HW partition ID rather than treating this
out-of-band. Equally, the existence of the priv field is crying out for
this patch to exist.

e183de0d3e ZFS: Clean up cppcheck warnings where relevant, leaked memory etc
In a message from Wolfgang Denk highlighting warnings from cppcheck,
the patch will address those that are correctly diagnosed. Some are
false-positives:

> [fs/zfs/zfs.c:937]: (error) Memory leak: l
dmu_read() allocates "l" if successful, so error-case should not free
it.
> [fs/zfs/zfs.c:1141]: (error) Memory leak: dnbuf
dmu_read() allocates "dnbuf" if successful, so error-case should not
free it.
> [fs/zfs/zfs.c:1372]: (error) Memory leak: osp
zio_read() allocates "osp" if successful, so error-case should
not free it.
> [fs/zfs/zfs.c:1726]: (error) Memory leak: nvlist
int_zfs_fetch_nvlist() allocates "nvlist" if successful, so error-case
should not free it.
