linux.git/include/linux/ufs_fs.h, branch master

drop linux/ufs_fs.h from userspace export and relocate it to fs/ufs/ufs_fs.h

2008-02-08T17:22:39+00:00

Per previous discussions about cleaning up ufs_fs.h, people just want
this straight up dropped from userspace export.  The only remaining
consumer (silo) has been fixed a while ago to not rely on this header.
This allows use to move it completely from include/linux/ to fs/ufs/
seeing as how the only in-kernel consumer is fs/ufs/.

ufs: move non-layout parts of ufs_fs.h to fs/ufs/

2007-10-17T15:42:51+00:00

Move prototypes and in-core structures to fs/ufs/ similar to what most
other filesystems already do.

I made little modifications: move also ufs debug macros and
mount options constants into fs/ufs/ufs.h, this stuff
also private for ufs.

Add in SunOS 4.1.x compatible mode for UFS

2007-10-17T15:42:49+00:00

Add in support for SunOS 4.1.x flavor of BSD 4.2 UFS filing system Macros have
been put in to alow suport for the old static table Cylinder Groups but this
implementation does not use them yet.

This also fixes Solaris UFS filing system access by disabling fast symbolic
links as Sun's version of UFS does not support on-disk fast symbolic links.

Tested by:
  Ppartitioning a new disk using SunOS 4.1.1, creating a UFS filing system on
  one of the partitions and writing some files to the filing system.
  Using Linux-2.6.22 (patched) to read the files and then write a shed load of
  files to the UFS partition.
  Using SunOS 4.1.1 to verify the filing system is OK and to check the files.
The test host is a sun4c SS1 Clone.

[PATCH] ufs2: more correct work with time

2007-03-17T02:25:03+00:00

This patch corrects work with time in UFS2 case.

1) According to UFS2 disk layout modification/access and so on "time"
   should be hold in two variables one 64bit for seconds and another 32bit for
   nanoseconds,

   at now for some unknown reason we suppose that "inode time" holds in
   three variables 32bit for seconds, 32bit for milliseconds and 32bit for
   nanoseconds.

2) We set amount of nanoseconds in "VFS inode" to 0 during read, instead of
   getting values from "on disk inode"(this should close
   http://bugzilla.kernel.org/show_bug.cgi?id=7991).

[PATCH] mark struct inode_operations const 3

2007-02-12T17:48:46+00:00

Many struct inode_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

[PATCH] ufs2 write: block allocation update

2007-02-12T17:48:40+00:00

Patch adds ability to work with 64bit metadata, this made by replacing work
with 32bit pointers by inline functions.

[PATCH] ufs2 write: inodes write

2007-02-12T17:48:40+00:00

This patch adds into write inode path function to write UFS2 inode, and
modifys allocate inode path to allocate and init additional inode chunks.

Also some cleanups:
- remove not used parameters in some functions
- remove i_gen field from ufs_inode_info structure,
there is i_generation in inode structure with same purposes.

[PATCH] export ufs_fs.h to userspace

2007-02-12T17:48:30+00:00

Was ufs_fs.h purposefully not exported to userspace or did it just slip
through the cracks ?  assuming the latter scenario, the attached patch touches
up the relationship between ufs_fs.h and its sub headers (like ufs_fs_sb.h) so
that we can export it ...  the silo bootloader takes advantage of this header
for example.

[PATCH] ufs: restore back support of openstep

2007-02-09T17:25:46+00:00

This is a fix of regression, which triggered by ~2.6.16.

Patch with name ufs-directory-and-page-cache-from-blocks-to-pages.patch: in
additional to conversation from block to page cache mechanism added new
checks of directory integrity, one of them that directory entry do not
across directory chunks.

But some kinds of UFS: OpenStep UFS and Apple UFS (looks like these are the
same filesystems) have different directory chunk size, then common
UFSes(BSD and Solaris UFS).

So this patch adds ability to works with variable size of directory chunks,
and set it for ufstype=openstep to right size.

Tested on darwin ufs.

[PATCH] fix UFS superblock alignment issues

2006-11-03T20:27:56+00:00

ufs2 fails to mount on x86_64, claiming bad magic.  This is because
ufs_super_block_third's fs_un1 member is padded out by 4 bytes for 8-byte
alignment, pushing down the rest of the struct.

Forcing this to be packed solves it.  I took a quick look over other
on-disk structures and didn't immediately find other problems.  I was able
to mount & ls a populated ufs2 filesystem w/ this change.
