We're hitting some issues with uninitialized struct padding, flagged by kmsan. They appear to be falso positives, otherwise bch2_accounting_validate() would have flagged them as "junk at end". But for now, we'll need to initialize disk_accounting_pos with memset(). This adds a new helper, bch2_disk_accounting_mod2(), that initializes a disk_accounting_pos and does the accounting mod all at once - so overall things actually get slightly more ergonomic. BCH_DISK_ACCOUNTING_replicas keys are left for now; KMSAN isn't warning about them and they're a bit special. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
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.
