parse errors in ifdefs

2007-06-01T15:18:28+00:00

Fix various bits of obviously-busted code which we're not happening to
compile, due to ifdefs.

Fix possible UDF data corruption

2007-06-01T15:18:27+00:00

update_next_aext() could possibly rewrite values in elen and eloc, possibly
leading to data corruption when rewriting a file.  Use temporary variables
instead.  Also advance cur_epos as it can also point to an indirect extent
pointer.

Detach sched.h from mm.h

2007-05-21T16:18:19+00:00

First thing mm.h does is including sched.h solely for can_do_mlock() inline
function which has "current" dereference inside. By dealing with can_do_mlock()
mm.h can be detached from sched.h which is good. See below, why.

This patch
a) removes unconditional inclusion of sched.h from mm.h
b) makes can_do_mlock() normal function in mm/mlock.c
c) exports can_do_mlock() to not break compilation
d) adds sched.h inclusions back to files that were getting it indirectly.
e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were
   getting them indirectly

Net result is:
a) mm.h users would get less code to open, read, preprocess, parse, ... if
   they don't need sched.h
b) sched.h stops being dependency for significant number of files:
   on x86_64 allmodconfig touching sched.h results in recompile of 4083 files,
   after patch it's only 3744 (-8.3%).

Cross-compile tested on

	sparc64 sparc64-up
	um-x86_64
	x86_64 x86_64-up x86_64-defconfig x86_64-allnoconfig

as well as my two usual configs.

Remove SLAB_CTOR_CONSTRUCTOR

2007-05-17T12:23:04+00:00

SLAB_CTOR_CONSTRUCTOR is always specified. No point in checking it.

sb_read may return NULL, let's explicitly check it.

udf: support files larger than 1G

2007-05-08T18:15:21+00:00

Make UDF work correctly for files larger than 1GB.  As no extent can be
longer than (1<<30)-blocksize bytes, we have to create several extents if a
big hole is being created.  As a side-effect, we now don't discard
preallocated blocks when creating a hole.

udf: add assertions

2007-05-08T18:15:21+00:00

Add a few assertions into udf_discard_prealloc() to check that the file is
sane (mostly helps debugging further patches ;).

Make UDF use get_bh() instead of directly accessing b_count and use
brelse() instead of udf_release_data() which does just brelse()...

UDF: introduce struct extent_position

2007-05-08T18:15:21+00:00

Introduce a structure extent_position to store a position of an extent and
the corresponding buffer_head in one place.

udf: use sector_t and loff_t for file offsets

2007-05-08T18:15:21+00:00

Use sector_t and loff_t for file offsets in UDF filesystem.  Otherwise an
overflow may occur for long files.  Also make inode_bmap() return offset in
the extent in number of blocks instead of number of bytes - for most
callers this is more convenient.
