Currently TOMOYO holds SRCU lock upon open() and releases it upon close() because list elements stored in the "struct tomoyo_io_buffer" instances are accessed until close() is called. However, such SRCU usage causes lockdep to complain about leaving the kernel with SRCU lock held. This patch solves the warning by holding/releasing SRCU upon each read()/write(). This patch is doing something similar to calling kfree() without calling synchronize_srcu(), by selectively deferring kfree() by keeping track of the "struct tomoyo_io_buffer" instances.
