The patch titled Subject: percpu_rw_semaphore: introduce CONFIG_PERCPU_RWSEM has been removed from the -mm tree. Its filename was percpu_rw_semaphore-introduce-config_percpu_rwsem.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Oleg Nesterov <oleg@xxxxxxxxxx> Subject: percpu_rw_semaphore: introduce CONFIG_PERCPU_RWSEM Currently only block_dev and uprobes use percpu_rw_semaphore, add the config option selected by BLOCK || UPROBES.
