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)
