udf: Replace bkl with the UDF_I(inode)->i_data_sem for protect udf_inode_info struct
Replace bkl with the UDF_I(inode)->i_data_sem rw semaphore in
udf_release_file(), udf_symlink(), udf_symlink_filler(), udf_get_block(),
udf_block_map(), and udf_setattr(). The rule now is that any operation
on regular file's or symlink's extents (or generally allocation information
including goal block) needs to hold i_data_sem.
This work was supported by a hardware donation from the CE Linux Forum.
