Hi
This patchset contains various UDF fs cleanups.
It deprecates two patchsets I sent lately:
http://lkml.org/lkml/2008/1/5/196 [PATCH 0/6] udf: improve code related to super_block v3
http://lkml.org/lkml/2008/1/5/211 [PATCH 0/7] udf: more cleanups
I hope I addressed all comments sent by Christoph Hellwig and Jan Kara.
Thanks for review!
[PATCH 01/16] udf: fix coding style of super.c
[PATCH 02/16] udf: remove some ugly macros
[PATCH 03/16] udf: convert UDF_SB_ALLOC_PARTMAPS macro to udf_sb_alloc_partition_maps function
[PATCH 04/16] udf: check if udf_load_logicalvol failed
[PATCH 05/16] udf: convert macros related to bitmaps to functions
[PATCH 06/16] udf: move calculating of nr_groups into helper function
[PATCH 07/16] udf: fix sparse warnings (shadowing & mismatch between declaration and definition)
[PATCH 08/16] udf: fix coding style
[PATCH 09/16] udf: create common function for tag checksumming
[PATCH 10/16] udf: create common function for changing free space counter
[PATCH 11/16] udf: replace loops coded with goto to real loops
[PATCH 12/16] udf: convert byte order of constant instead of variable
[PATCH 13/16] udf: remove UDF_I_* macros and open code them
[PATCH 14/16] udf: cache struct udf_inode_info
These patches are new:
[PATCH 15/16] udf: fix udf_debug macro
[PATCH 16/16] udf: improve readability of udf_load_partition

fix coding style errors found by checkpatch:
- assignments in if conditions
- braces {} around single statement blocks
- no spaces after commas
- printks without KERN_*
- lines longer than 80 characters
before: total: 50 errors, 207 warnings, 1835 lines checked
after: total: 0 errors, 164 warnings, 1872 lines checked
all 164 warnings left are lines longer than 80 characters;
this file has too much indentation with really long expressions
to break all those lines now; will fix later

udf_debug should be enclosed with do { } while (0)
to be safely used in code like below:
if (something)
udf_debug();
else
anything;
(Otherwise compiler will not compile it with:
"error: expected expression before 'else'")

Maybe because you use the function for both increasing and decreasing
free space, you could call is udf_add_free_space?

I think macro like le32_add_cpu() just went into the kernel so you could
use that...
