Instantiate glocks outside of the glock state engine: there is no real reason for instantiating them inside the glock state engine; it only complicates the code. Instead, instantiate them in gfs2_glock_wait() and gfs2_glock_async_wait() using the new gfs2_glock_holder_ready() helper. On top of that, the only other place that acquires a glock without using gfs2_glock_wait() or gfs2_glock_async_wait() is gfs2_upgrade_iopen_glock(), so call gfs2_glock_holder_ready() there as well. If a dinode has a pending truncate, the glock-specific instantiate function for inodes wakes up the truncate function in the quota daemon. Waiting for the completion of the truncate was previously done by the glock state engine, but we now need to wait in inode_go_instantiate(). This also means that gfs2_instantiate() will now no longer return any "special" error codes. Signed-off-by: Andreas Gruenbacher <agruenba@redhat.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.
