• fa9ee9c4b   include/linux/err.h: add a function to cast error-pointers to a return value ... Browse Code »

  PTR_RET() can be used if you have an error-pointer and are only interested
  in the eventual error value, but not the pointer. Yields the usual 0 for
  no error, -ESOMETHING otherwise.

• e47103b1a   err.h: add __must_check to error pointer handlers ... Browse Code »

  Add __must_check to error pointer handlers to have the compiler warn about
  mistakes like:

  if (err)
  ERR_PTR(err);

  It found two bugs:

  Mar 12 Nikula Jani [PATCH] enclosure: fix error path - actually return ERR_PTR() on error
  Mar 12 Nikula Jani [PATCH] sunrpc: fix error path - actually return ERR_PTR() on error

• 603c4ba96   err.h: add helper function to simplify pointer error checking ... Browse Code »

  There are quite a few instances in the kernel of checks of pointers both
  against NULL and against the errno range, handling both cases identically.
  This additional helper function would simplify such code.

  Add an ERR_CAST() function to complement ERR_PTR and co. for the purposes
  of casting an error entyped as one pointer type to an error of another
  pointer type whilst making it explicit as to what is going on.

  This provides a replacement for the ERR_PTR(PTR_ERR(p)) construct.

• 07ab67c8d   Fix get_unmapped_area sanity tests ... Browse Code »

  As noted by Chris Wright, we need to do the full range of tests regardless
  of whether MAP_FIXED is set or not, so re-organize get_unmapped_area()
  slightly to do the sanity checks unconditionally.

  Initial git repository build. I'm not bothering with the full history,
  even though we have it. We can create a separate "historical" git
  archive of that later if we want to, and in the meantime it's about
  3.2GB when imported into git - space that would just make the early
  git days unnecessarily complicated, when we don't have a lot of good
  infrastructure for it.

  Let it rip!
