Yanfeng Liu 102a62c7e3 mm/mm_gran: remove allocation size limitation
This patch refactors granule allocator to remove the 32 granules
limitation with the help of a gran_range_s structure and related
functions, see "mm_grantable.h" for details.

Below are the major functions explaining how this works:

- The gran_match() checks if a gran range all in the given state.
  it gives last mismatch position when fails free range matching.
- The gran_search() tries to find the position of a free range.
  It leverages last mismatch position from gran_match() to speed
  up the search.

range size handling is mainly in gran_match() and gran_set_().

Gregory Nutt 156963a903 Check return from nxsem_wait_initialize()
Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution:  Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly.  This commit is only for those files under fs/tmpfs and fs/spiffs.  Still do do:  The rest of fs/ and all of drivers/ and arch/.

This commit is only for those files under graphics/, mm/, net/, sched/, wireless/bluetooth.

Still to do:  Files under fs/, drivers/, and arch.  The last is 116 files and will take some effort.

Gregory Nutt 62b8026976 Remove CONFIG_GRAN_SINGLE. It adds no technical benefit (other than some minor reduction in the number of interface arguments) but adds a lot of code complexity. Better without it. 2017-11-14 11:47:12 -06:00
