Simplify tracking of the range processed by using cur_alloc_size only to store the reserved part that may fail to the allocated extent. Remove the ram_size as well since it is always equal to cur_alloc_size in the context. Advance the start in normal path until extent allocation succeeds and keep the start unchanged in the error handling path. Passed the fstest generic/475 test for a hundred times with quota enabled. And a modified generic/475 test by removing the sleep time for a hundred times. About one tenth of the tests do enter the error handling path due to fail to reserve extent.

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.
