We have this entangled error checks early at btrfs_page_mkwrite(): 1) Try to reserve delalloc space by calling btrfs_delalloc_reserve_space() and storing the return value in the ret2 variable; 2) If the reservation succeed, call file_update_time() and store the return value in ret2 and also set the local variable 'reserved' to true (1); 3) Then do an error check on ret2 to see if any of the previous calls failed and if so, jump either to the 'out' label or to the 'out_noreserve' label, depending on whether 'reserved' is true or not. This is unnecessarily complex. Instead change this to a simpler and more straightforward approach: 1) Call btrfs_delalloc_reserve_space(), if that returns an error jump to the 'out_noreserve' label; 2) The call file_update_time() and if that returns an error jump to the 'out' label. Like this there's less nested if statements, no need to use a local variable to track if space was reserved and if statements are used only to check errors. Also move the call to extent_changeset_free() out of the 'out_noreserve' label and under the 'out' label since the changeset is allocated only if the call to reserve delalloc space succeeded.

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 reStructuredText 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.
