There is no point in maintaining a separate funciton __nvmf_host_find() that has only one caller nvmf_host_add() especially when caller and callee both are small enough to merge. Due to this we are actually repeating the error handling code in both callee and caller for no reason that can be avoided, but instead we have to read both function to establish the correctness along with additional lockdep warning check due to involved locking. Just open code __nvmf_host_find() in nvme_host_alloc() with appropriate comment that removes repeated error checks in the callee/caller and lockdep check that is needed for the nvmf_hosts_mutex involvement, diffstats :- drivers/nvme/host/fabrics.c | 75 +++++++++++++------------------------ 1 file changed, 27 insertions(+), 48 deletions(-) Signed-off-by: Chaitanya Kulkarni <kch@nvidia.com> Reviewed-by: Sagi Grimberg <sagi@grimberg.me> Reviewed-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Max Gurtovoy <mgurtovoy@nvidia.com> Signed-off-by: Keith Busch <kbusch@kernel.org>
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.
