We may end up in a situation where allocating the buffer for the sorted journal_keys fails - but it would likely succeed, post compaction where we drop duplicates. We've had reports of this allocation failing, so this adds a slowpath to do the compaction incrementally. This is only a band-aid fix; we need to look at limiting the number of keys in the journal based on the amount of system RAM. 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 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.
