Linux kernel source tree
f022499f24
If we are doing an unlink for log replay, we are updating the directory's mtime and ctime to the current time, and this is incorrect since it should stay with the mtime and ctime that were set when the directory was logged. This is the same as when adding a link to an inode during log replay (with btrfs_add_link()), where we want the mtime and ctime to be the values that were in place when the inode was logged. This was found with generic/547 using LOAD_FACTOR=20 and TIME_FACTOR=20, where due to large log trees we have longer log replay times and fssum could detect a mismatch of the mtime and ctime of a directory. Fix this by skipping the mtime and ctime update at __btrfs_unlink_inode() if we are in log replay context (just like btrfs_add_link()).

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.
