ufs: fix truncated values handling 64 bit metadata

2011-05-27T00:12:33+00:00

Originally i_lastfrag was 32 bits but then we added support for handling
64 bit metadata and it became a 64 bit variable.  That was during 2007, in
54fb996ac15c "[PATCH] ufs2 write: block allocation update".  Unfortunately
these casts got left behind so the value got truncated to 32 bit again.

remove SWRITE* I/O types

2010-08-18T05:09:01+00:00

These flags aren't real I/O types, but tell ll_rw_block to always
lock the buffer instead of giving up on a failed trylock.

Instead add a new write_dirty_buffer helper that implements this semantic
and use it from the existing SWRITE* callers.  Note that the ll_rw_block
code had a bug where it didn't promote WRITE_SYNC_PLUG properly, which
this patch fixes.

In the ufs code clean up the helper that used to call ll_rw_block
to mirror sync_dirty_buffer, which is the function it implements for
compound buffers.

ufs: Remove dead quota code

2010-05-24T12:10:19+00:00

UFS quota is non-functional at least since 2.6.12 because dq_op was set
to NULL. Since the filesystem exists mainly to allow cooperation with Solaris
and quota format isn't standard, just remove the dead code.

dquot: cleanup space allocation / freeing routines

2010-03-04T23:20:28+00:00

Get rid of the alloc_space, free_space, reserve_space, claim_space and
release_rsv dquot operations - they are always called from the filesystem
and if a filesystem really needs their own (which none currently does)
it can just call into it's own routine directly.

Move shared logic into the common __dquot_alloc_space,
dquot_claim_space_nodirty and __dquot_free_space low-level methods,
and rationalize the wrappers around it to move as much as possible
code into the common block for CONFIG_QUOTA vs not.  Also rename
all these helpers to be named dquot_* instead of vfs_dq_*.

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] ufs: zeroize the rest of block in truncate

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

This patch fix behaviour in such test scenario:

  lseek(fd, BIG_OFFSET)
  write(fd, buf, sizeof(buf))
  truncate(BIG_OFFSET)
  truncate(BIG_OFFSET + sizeof(buf))
  read(fd, buf...)

Because of if file big enough(BIG_OFFSET) we start allocate space by block,
ordinary block size > page size, so we should zeroize the rest of block in
truncate(except last framgnet, about which VFS should care), to not get
garbage, when we extend file.

Also patch corrects conversion from pointer to block to physical block number,
this helps in case of not common used UFS types.

And add to debug output inode number.
