The new convention is that functions that handle transaction restarts within an existing transaction context should return -BCH_ERR_transaction_restart_nested when they did so, since they invalidated the outer transaction context. This also means bch2_btree_delete_range_trans() is changed to only call bch2_trans_begin() after a transaction restart, not on every loop iteration. This is to fix a bug in fsck, in check_inode() when we truncate an inode with BCH_INODE_I_SIZE_DIRTY set. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
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.
