Inode allocation can require block allocation for physical inode chunk allocation, inode btree record insertion, and/or directory block allocation for entry insertion. Any of these block allocation requests can require AGFL fixups prior to the actual allocation. Update the common file creation transacions to defer AGFL frees from these contexts to avoid too much log reservation consumption per-transaction. Since these transactions are already passed down through the btree cursors and da_args structure, this simply requires to attach dfops to the transaction. Note that this covers tr_create, tr_mkdir and tr_symlink. Other transactions such as tr_create_tmpfile do not already make use of deferred operations and so are left alone for the time being.

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.
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.
