The function btrfs_check_can_nocow() now has two completely different call patterns. For nowait variant, callers don't need to do any cleanup. While for wait variant, callers need to release the lock if they can do nocow write. This is somehow confusing, and is already a problem for the exported btrfs_check_can_nocow(). So this patch will separate the different patterns into different functions. For nowait variant, the function will be called check_nocow_nolock(). For wait variant, the function pair will be btrfs_check_nocow_lock() btrfs_check_nocow_unlock().

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.
