staging: android: ashmem: lseek failed due to no FMODE_LSEEK.

2017-04-08T10:13:11Z

vfs_llseek will check whether the file mode has FMODE_LSEEK, no return failure. But ashmem can be lseek, so add FMODE_LSEEK to ashmem file. Comment From Greg Hackmann: ashmem_llseek() passes the llseek() call through to the backing shmem file. 91360b02ab48 ("ashmem: use vfs_llseek()") changed this from directly calling the file's llseek() op into a VFS layer call. This also adds a check for the FMODE_LSEEK bit, so without that bit ashmem_llseek() now always fails with -ESPIPE.

sched/headers: Prepare for new header dependencies before moving code to

We are going to split out of , which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder file that just maps to to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.

mm, fs: reduce fault, page_mkwrite, and pfn_mkwrite to take only vmf

2017-02-25T01:46:54Z

->fault(), ->page_mkwrite(), and ->pfn_mkwrite() calls do not need to take a vma and vmf parameter when the vma already resides in vmf. Remove the vma parameter to simplify things.

Pull staging/iio driver updates from Greg KH: "Here is the big staging and iio driver patchsets for 4.11-rc1. We almost broke even this time around, with only a few thousand lines added overall, as we removed the old and obsolete i4l code, but added some new drivers for the RPi platform, as well as adding some new IIO drivers.
