Add macros for nilfs_(sb, fmt, ...) and convert the uses of
'nilfs_msg(sb, KERN_, ...)' to 'nilfs_(sb, ...)' so nilfs2
uses a logging style more like the typical kernel logging style.Miscellanea:
o Realign arguments for these uses

Add code to check sizes of on-disk data of metadata files such as inode
size, segment usage size, DAT entry size, and checkpoint size. Although
these sizes are read from disk, the current implementation doesn't check
them.If these sizes are not sane on disk, it can cause out-of-range access to
metadata or memory access overrun on metadata block buffers due to
overflow in sundry calculations.Both lower limit and upper limit of metadata sizes are verified to
prevent these issues.Signed-off-by: Ryusuke Konishi

This is a trivial patch to delete unnecessary condition in nilfs_dat_translate.
nilfs_dat_translate() will asign translated address to *blocknrp if blocknrp
is not NULL. However the condition is unneeded, because all callers of
nilfs_dat_translate() pass blocknrp properly.Signed-off-by: Jiro SEKIBA

Will displace nilfs_mdt_read_inode_direct function with an individual

Nilfs has some ioctl commands to read out metadata from meta data
files:- NILFS_IOCTL_GET_CPINFO for checkpoint file,
- NILFS_IOCTL_GET_SUINFO for segment usage file, and
- NILFS_IOCTL_GET_VINFO for Disk Address Transalation (DAT) file,
respectively.Every routine on these metadata files is implemented so that it allows
future expansion of on-disk format. But, the above ioctl commands do
not support expansion even though nilfs_argv structure can handle
arbitrary size for data exchanged via ioctl.This allows future expansion of the following structures which give
basic format of the "get information" ioctls:- struct nilfs_cpinfo
- struct nilfs_suinfo
- struct nilfs_vinfoSo, this introduces forward compatility of such ioctl commands.
In this patch, a sanity check in nilfs_ioctl_get_info() function is
changed to accept larger data structure [1], and metadata read
routines are rewritten so that they become compatible for larger
structures; the routines will just ignore the remaining fields which
the current version of nilfs doesn't know.[1] The ioctl function already has another upper limit (PAGE_SIZE
against a structure, which appears in nilfs_ioctl_wrap_copy
function), and this will not cause security problem.Signed-off-by: Ryusuke Konishi

Pekka Enberg advised me:
> It would be nice if BUG(), BUG_ON(), and panic() calls would be
> converted to proper error handling using WARN_ON() calls. The BUG()
> call in nilfs_cpfile_delete_checkpoints(), for example, looks to be
> triggerable from user-space via the ioctl() system call.This will follow the comment and keep them to a minimum.

This adds the disk address translation file (DAT) whose primary function
is to convert virtual disk block numbers to actual disk block numbers.The virtual block numbers of NILFS are associated with checkpoint
generation numbers, and this file also provides functions to manage the
