linux.git/fs/ufs/ialloc.c, branch v2.6.26

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.

[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] 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] inode-diet: Eliminate i_blksize from the inode structure

2006-09-27T15:26:18+00:00

This eliminates the i_blksize field from struct inode.  Filesystems that want
to provide a per-inode st_blksize can do so by providing their own getattr
routine instead of using the generic_fillattr() function.

Note that some filesystems were providing pretty much random (and incorrect)
values for i_blksize.

[PATCH] ufs: ubh_ll_rw_block cleanup

2006-06-25T17:01:04+00:00

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".

[PATCH] ufs: make fsck -f happy

2006-06-25T17:01:04+00:00

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.

[PATCH] ufs: easy debug

2006-06-25T17:01:03+00:00

Currently to turn on debug mode "user" has to edit ~10 files, to turn off he
has to do it again.

This patch introduce such changes:
1)turn on(off) debug messages via ".config"
2)remove unnecessary duplication of code
3)make "UFSD" macros more similar to function
4)fix some compiler warnings

[PATCH] ufs: wrong type cast

2006-06-25T17:01:02+00:00

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.
