 - Don't fail listing extended attributes in kernfs when no extended
   attributes are set

 - Fix the return value in coredump_parse()

 - Fix the error handling for unbuffered writes in netfs

 - Fix broken data integrity guarantees for O_SYNC writes via iomap

 - Fix UAF in __mark_inode_dirty()

 - Keep inode->i_blkbits constant in fuse

 - Fix coredump selftests

 - Fix get_unused_fd_flags() usage in do_handle_open()

 - Rename EXPORT_SYMBOL_GPL_FOR_MODULES to EXPORT_SYMBOL_FOR_MODULES

 - Fix use-after-free in bh_read()

 - Fix incorrect lflags value in the move_mount() syscall
