Linux kernel source tree
c431d3867e
Previously, ext4_mb_mark_context is only called under fast commit replay path, so there is no valid handle when we update block bitmap and group descriptor. This patch try to extend ext4_mb_mark_context to be used by code under journal. There are several improvement: 1. Add "handle_t *handle" to struct ext4_mark_context to journal block bitmap and group descriptor update inside ext4_mb_mark_context (the added journal code is based on ext4_mb_mark_diskspace_used where ext4_mb_mark_context is going to be used.) 2. Adds a flag argument to ext4_mb_mark_context() which controls a. EXT4_MB_BITMAP_MARKED_CHECK - whether block bitmap checking is needed. b. EXT4_MB_SYNC_UPDATE - whether dirty buffers (bitmap and group descriptor) needs sync.

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.
