Hi KONISHI Ryusuke,
Three new patches based on nilfs2/for-next branch. New code has been built and
loaded successfully, and also passed a light-weight reads and writes test.
Thanks,
Li Hong

Subject: [PATCH 1/3] nilfs2: remove nilfs_segctor_init() in segment.c
There are only two lines of code in nilfs_segctor_init(). From a logic design
view, the first line 'sci->sc_seq_done = sci->sc_seq_request;' should be put in
nilfs_segctor_new(). Even in nilfs_segctor_new(), this initialization is
needless because sci is kzalloc-ed. So nilfs_segctor_init() is only a wrap call
to nilfs_segctor_start_thread(). This removes an indirect call overhead.
