[PATCH] ext3: multile block allocate little endian fixes

2006-05-04T03:05:41+00:00

Some places in ext3 multiple block allocation code (in 2.6.17-rc3) don't
handle the little endian well.  This was resulting in *wrong* block numbers
being assigned to in-memory block variables and then stored on disk
eventually.  The following patch has been verified to fix an ext3
filesystem failure when run ltp test on a 64 bit machine.

[PATCH] protect ext3 ioctl modifying append_only, immutable, etc. with i_mutex

2006-04-26T14:52:21+00:00

All modifications of ->i_flags in inodes that might be visible to
somebody else must be under ->i_mutex.  That patch fixes ext3 ioctl()
setting S_APPEND and friends.

[PATCH] forgotten ->b_data in memcpy() call in ext3/resize.c (oopsable)

2006-04-26T14:52:21+00:00

sbi->s_group_desc is an array of pointers to buffer_head.  memcpy() of
buffer size from address of buffer_head is a bad idea - it will generate
junk in any case, may oops if buffer_head is close to the end of slab
page and next page is not mapped and isn't what was intended there.
IOW, ->b_data is missing in that call.  Fortunately, result doesn't go
into the primary on-disk data structures, so only backup ones get crap
written to them; that had allowed this bug to remain unnoticed until
now.

[PATCH] Introduce sys_splice() system call

2006-03-30T20:28:18+00:00

This adds support for the sys_splice system call. Using a pipe as a
transport, it can connect to files or sockets (latter as output only).

From the splice.c comments:

   "splice": joining two ropes together by interweaving their strands.

   This is the "extended pipe" functionality, where a pipe is used as
   an arbitrary in-memory buffer. Think of a pipe as a small kernel
   buffer that you can use to transfer data from one end to the other.

   The traditional unix read/write is extended with a "splice()" operation
   that transfers data buffers to or from a pipe buffer.

   Named by Larry McVoy, original implementation from Linus, extended by
   Jens to support splicing to files and fixing the initial implementation
   bugs.

[PATCH] Make most file operations structs in fs/ const

2006-03-28T17:16:06+00:00

This is a conversion to make the various file_operations structs in fs/
const.  Basically a regexp job, with a few manual fixups

The goal is both to increase correctness (harder to accidentally write to
shared datastructures) and reducing the false sharing of cachelines with
things that get dirty in .data (while .rodata is nicely read only and thus
cache clean)

[PATCH] ext3: "nobh" writeback support for filesystems blocksize < pagesize

2006-03-26T16:57:02+00:00

There is no valid reason why we can't support "nobh" option for filesystems
with blocksize != PAGESIZE.

This patch lets them use "nobh" option for writeback mode for blocksize <
pagesize.

[PATCH] ext3: multi-block get_block()

2006-03-26T16:57:02+00:00

Mingming Cao recently added multi-block allocation support for ext3,
currently used only by DIO.  I added support to map multiple blocks for
mpage_readpages().  This patch add support for ext3_get_block() to deal
with multi-block mapping.  Basically it renames ext3_direct_io_get_blocks()
as ext3_get_block().
