It is now clear that nilfs_bmap_write() is only used to finalize logs written to disk. Concurrent bmap modification operations are not performed on bmaps in this context. Additionally, this function does not modify data used in read-only operations such as bmap lookups. Therefore, there is no need to acquire bmap->b_sem in nilfs_bmap_write(), so delete it.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
