Call trace to assign ac_f_ex: ext4_mb_use_best_found ac->ac_f_ex = ac->ac_b_ex; ext4_mb_new_preallocation ext4_mb_new_group_pa ac->ac_f_ex = ac->ac_b_ex; ext4_mb_new_inode_pa ac->ac_f_ex = ac->ac_b_ex; Actually allocated blocks is already stored in ac_f_ex in ext4_mb_use_best_found, so there is no need to assign ac_f_ex in ext4_mb_new_group_pa and ext4_mb_new_inode_pa. Just remove repeat assignment to ac_f_ex in ext4_mb_new_group_pa and ext4_mb_new_inode_pa.

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.
