Linux kernel source tree

The 'struct attribute' flex array contains some struct lock_class_key's which become big when lockdep is turned on. Big enough that some drivers will not load when CONFIG_PROVE_LOCKING=y because they cannot allocate enough memory: WARNING: CPU: 36 PID: 8 at mm/page_alloc.c:5350 __alloc_pages+0x27e/0x3e0 Call Trace: kmalloc_order+0x2a/0xb0 kmalloc_order_trace+0x19/0xf0 __kmalloc+0x231/0x270 ib_setup_port_attrs+0xd8/0x870 [ib_core] ib_register_device+0x419/0x4e0 [ib_core] bnxt_re_task+0x208/0x2d0 [bnxt_re] Link: https://lore.kernel.org/r/20211019002656.17745-1-wangyugui@e16-tech.com Signed-off-by: wangyugui <wangyugui@e16-tech.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.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.
