udf: Remove unnecessary bkl usages
The udf_readdir(), udf_lookup(), udf_create(), udf_mknod(), udf_mkdir(), udf_rmdir(), udf_link(), udf_get_parent() and udf_unlink() seems already adequately protected by i_mutex held by VFS invoking calls. The udf_rename() instead should be already protected by lock_rename again by VFS. The udf_ioctl(), udf_fill_super() and udf_evict_inode() don't requires any further protection. 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>
