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. Signed-off-by: Alessio Igor Bogani <abogani@texware.it> Signed-off-by: Jan Kara <jack@suse.cz>
