In this round, we've focused on enhancing performance with regards to block
allocation, GC, and discard/in-place-update IO controls. There are a bunch
of clean-ups as well as minor bug fixes.
= Enhancement
- disable heap-based allocation by default
- issue small-sized discard commands by default
- change the policy of data hotness for logging
- distinguish IOs in terms of size and wbc type
- start SSR earlier to avoid foreground GC
- enhance data structures managing discard commands
- enhance in-place update flow
- add some more fault injection routines
- secure one more xattr entry
= Bug fix
- calculate victim cost for GC correctly
- remain correct victim segment number for GC
- race condition in nid allocator and initializer
- stale pointer produced by atomic_writes
- fix missing REQ_SYNC for flush commands
- handle missing errors in more corner cases

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
