* sh: no need to check return value of debugfs_create functionsGreg Kroah-Hartman2019-06-031-8/+3Star
| | | | | | | | | | | When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.

* sched/headers: Prepare for new header dependencies before moving code to ↵Ingo Molnar2017-03-021-0/+1
| | | | | | | | | | | | | | | | | | | | <linux/sched/task.h> We are going to split <linux/sched/task.h> out of <linux/sched.h>, which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder <linux/sched/task.h> file that just maps to <linux/sched.h> to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.

* sh: make mm/asids-debugfs explicitly non-modularPaul Gortmaker2016-07-311-4/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | The Makefile/Kconfig currently controlling compilation of this code is: obj-$(CONFIG_DEBUG_FS) += $(debugfs-y) debugfs-y := asids-debugfs.o lib/Kconfig.debug:config DEBUG_FS lib/Kconfig.debug: bool "Debug Filesystem" ....meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular code, so that when reading the driver there is no doubt it is builtin-only. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit.

* sh: provide generic arch_debugfs_dir.Paul Mundt2010-09-231-1/+1
| | | | | | | | | While sh previously had its own debugfs root, there now exists a common arch_debugfs_dir prototype, so we switch everything over to that. Presumably once more architectures start making use of this we'll be able to just kill off the stub kdebugfs wrapper. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Convert sh64 /proc/asids to debugfs and generic sh.Paul Mundt2008-12-221-0/+79
This converts the sh64 /proc/asids entry to debugfs and enables it for all SH parts that have debugfs enabled. On MMU systems this can be used to determine which processes are using which ASIDs which in turn can be used for finer grained cache tag analysis. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
