Patch adds ability to work with 64bit metadata, this made by replacing work
with 32bit pointers by inline functions.Signed-off-by: Evgeniy Dushistov

This patch fixes buggy behaviour of UFS
in such kind of scenario:
open(, O_TRUNC...)
ftruncate(, 1024)
ftruncate(, 0)Such a scenario causes ufs_panic and remount read-only. This happen
because of according to specification UFS should always allocate block for
last byte, and many parts of our implementation rely on this, but
`ufs_truncate' doesn't care about this.To make possible return error code and to know about old size, this patch
removes `truncate' from ufs inode_operations and uses `setattr' method to
call ufs_truncate.Signed-off-by: Evgeniy Dushistov

In ufs code there is function: ubh_ll_rw_block, it has parameter how many
ufs_buffer_head it should handle, but it always called with "1" on the place
of this parameter. This patch removes unused parameter of "ubh_ll_wr_block".Signed-off-by: Evgeniy Dushistov

ufs super block contains some statistic about file systems, like amount of
directories, free blocks, inodes and so on.UFS1 hold this information in one location and uses 32bit integers for such
information, UFS2 hold statistic in another location and uses 64bit integers.There is transition variant, if UFS1 has type 44BSD and flags field in super
block has some special value this mean that we work with statistic like UFS2
does. and this also means that nobody care about old(UFS1) statistic.So if start fsck against such file system, after usage linux ufs driver, it
found error: at now only UFS1 like statistic is updated.This patch should fix this. Also it contains some minor cleanup: CodingSytle
and remove unused variables.Signed-off-by: Evgeniy Dushistov

Super block of UFS usually has size >512, because of fragment size may be 512,
this cause some problems.Currently, there are two methods to work with ufs super block:
1) split structure which describes ufs super blocks into structures with
size b_data + bh[n]->b_size == bh[n + 1]->b_dataThe second variant may cause some problems in the future, and usage of two
variants cause unnecessary code duplication.This patch remove the second variant. Also patch contains some CodingStyle
fixes.Signed-off-by: Evgeniy Dushistov

The writing to UFS file system with block/fragment!=8 may cause bogus
behaviour. The problem in "ufs_bitmap_search" function, which doesn't work
correctly in "block/fragment!=8" case. The idea is stolen from BSD code.Signed-off-by: Evgeniy Dushistov

There are two ugly macros in ufs code:
#define UCPI_UBH ((struct ufs_buffer_head *)ucpi)
#define USPI_UBH ((struct ufs_buffer_head *)uspi)
when uspi looks like
struct {
struct ufs_buffer_head ;
}
and USPI_UBH has some sence,
ucpi looks like
struct {
struct not_ufs_buffer_head;
}To prevent bugs in future, this patch convert macros to inline function and
fix "ucpi" structure.Signed-off-by: Evgeniy Dushistov

Currently, ufs write support have two sets of problems: work with files and
work with directories.This series of patches should solve the first problem.
This patch is similar to http://lkml.org/lkml/2006/1/17/61 this patch
complements it.The situation the same: in ufs_trunc_(not direct), we read block, check if
count of links to it is equal to one, if so we finish cycle, if not
continue. Because of "count of links" always >=2 this operation cause
infinite cycle and hang up the kernel.Signed-off-by: Evgeniy Dushistov

Here is update of ufs cleanup patch, brought on by the recently fixed
ubh_get_usb_second() bug that made some ugly code rather painfully
obvious. It also includes- fix compilation warnings which appears if debug mode turn on
- remove unnecessary duplication of code to support UFS2I tested it on ufs1 and ufs2 file-systems.

There's a lack of parenthesis in fs/ufs/utils.h, so instead of the 512th
byte of buffer, the usb2 pointer will point to the nth structure of type
ufs_super_block_second.This can cause a mount-time oops if you're unlucky (especially with
DEBUG_PAGEALLOC, which is how Alexey Dobriyan saw this problem)Signed-off-by: Evgeniy Dushistov

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
