Merge branch 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-udf-2.6
* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-udf-2.6:
UDF: Close small mem leak in udf_find_entry()
udf: Fix directory corruption after extent merging
udf: Protect udf_file_aio_write from possible races
udf: Remove unnecessary bkl usages
udf: Use of s_alloc_mutex to serialize udf_relocate_blocks() execution
udf: Replace bkl with the UDF_I(inode)->i_data_sem for protect udf_inode_info struct
udf: Remove BKL from free space counting functions
udf: Call udf_add_free_space() for more blocks at once in udf_free_blocks()
udf: Remove BKL from udf_put_super() and udf_remount_fs()
udf: Protect default inode credentials by rwlock
udf: Protect all modifications of LVID with s_alloc_mutex
udf: Move handling of uniqueID into a helper function and protect it by a s_alloc_mutex
udf: Remove BKL from udf_update_inode
udf: Convert UDF_SB(sb)->s_flags to use bitops
fs/udf: Add printf format/argument verification
fs/udf: Use vzalloc
(Evil merge: this also removes the BKL dependency from the Kconfig file)
