2018-10-18doc: fix a typo in adding-syscalls.rstGuillaume Dore1-1/+1
There was a typo in adding-syscalls.rst that could mislead developers to add a C filename in a makefile instead of an object filename. This error, while not keeping developers from contributing could slow the development process down by introducing build errors.

2018-10-12docs/admin-guide: memory-hotplug: remove table of contentsMike Rapoport1-21/+0
Remove "manual" table of contents and leave only the ReST tag so that Sphinx will take care of TOC generation. Signed-off-by: Mike Rapoport <rppt@linux.vnet.ibm.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2018-10-12doc: printk-formats: Remove bogus kobject references for device nodesGeert Uytterhoeven2-14/+12
When converting from text to rst, the kobjects section and its sole subsection about device tree nodes were coalesced into a single section, yielding an inconsistent result. Remove all references to kobjects, as 1. Device tree object pointers are not compatible to kobject pointers (the former may embed the latter, though), and 2. there are no printk formats defined for kobject types. Update the vsprintf() source code comments to match the above.

2018-10-12Documentation: preempt-locking: Use better exampleAndrew Murray1-6/+6
The existing wording implies that the use of spin_unlock whilst irqs are disabled might trigger a reschedule. However the preemptible() test in preempt_schedule will prevent a reschedule if irqs are disabled. Lets improve the clarity of this wording to change the example from spin_unlock to cond_resched() and cond_resched_lock() as these are functions that will trigger a reschedule if the preempt count is 0 without testing that irqs are disabled. Also remove the 'Last Updated' line as this is not up to date and better tracked via GIT. Signed-off-by: Andrew Murray <andrew.murray@arm.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2018-10-12dm flakey: Document "error_writes" featureNikolay Borisov1-0/+4
Commit ef548c551e72 ("dm flakey: introduce "error_writes" feature") added the ability to dm flakey to error out writes in contrast to silently dropping it with 'drop_writes'. Unfortunately this feature is not currently documented and one has to be either familiar with the source code of dm flakey or check out xfstests sources to know of this parameter. So document it.

2018-10-12docs/completion.txt: Fix a couple of punctuation nitsJohn Garry1-3/+3
This patch fixes a couple of punctuation nits which can make the document more correct and readable. Also missing "()" are added to some function references for consistency.
