f2fs only support to config zstd compress level w/ a positive number due to layout design, but since commite0c1b49f5b("lib: zstd: Upgrade to latest upstream zstd version 1.4.10"), zstd supports negative compress level, so that zstd_min_clevel() may return a negative number, then w/ below mount option, .compress_level can be configed w/ a negative number, which is not allowed to f2fs, let's add check condition to avoid it. mount -o compress_algorithm=zstd:4294967295 /dev/sdx /mnt/f2fs Fixes:00e120b5e4("f2fs: assign default compression level") Signed-off-by: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
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.
