Christophe JAILLET	5a905e33b2	RDMA/hfi1: Constify struct mmu_rb_ops ... 'struct mmu_rb_ops' is not modified in this driver. Constifying this structure moves some data to a read-only section, so increase overall security. On a x86_64, with allmodconfig, as an example: Before: ====== text data bss dec hex filename 10879 164 0 11043 2b23 drivers/infiniband/hw/hfi1/pin_system.o After: ===== text data bss dec hex filename 10907 140 0 11047 2b27 drivers/infiniband/hw/hfi1/pin_system.o Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Link: https://lore.kernel.org/r/b826dd05eefa5f4d6a7a1b4d191eaf37c714ed04.1719259997.git.christophe.jaillet@wanadoo.fr Signed-off-by: Leon Romanovsky <leon@kernel.org> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>	2024-06-26 10:53:29 -03:00
Brendan Cunningham	d2c0234634	RDMA/hfi1: Move user SDMA system memory pinning code to its own file ... Move user SDMA system memory page-pinning code from user_sdma.c to pin_system.c. Put declarations for non-static functions in pinning.h. System memory pinning is necessary for processing user SDMA requests but actual steps are invisible to user SDMA request-processing code. Moving system memory pinning code for user SDMA to its own file makes this distinction apparent. These changes have no effect on userspace.
