Linux kernel source tree
9cb5f15d88
This series changes the directory update code to retain the ILOCK on all files involved in a rename until the end of the operation. The upcoming parent pointers patchset applies parent pointers in a separate chained update from the actual directory update, which is why it is now necessary to keep the ILOCK instead of dropping it after the first transaction in the chain. As a side effect, we no longer need to hold the IOLOCK during an rmapbt scan of inodes to serialize the scan with ongoing directory updates. This has been running on the djcloud for months with no problems. Enjoy! Signed-off-by: Darrick J.

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 reStructuredText 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.
