Allow a new process to take ownership of a previously owned table, useful mostly for firewall management services restarting or suspending when idle. By extending __NFT_TABLE_F_UPDATE, the on/off/on check in nf_tables_updtable() also covers table adoption, although it is actually not needed: Table adoption is irreversible because nf_tables_updtable() rejects attempts to drop NFT_TABLE_F_OWNER so table->nlpid setting can happen just once within the transaction. If the transaction commences, table's nlpid and flags fields are already set and no further action is required. If it aborts, the table returns to orphaned state.

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.
