list: introduce list_last_entry(), use list_{first,last}_entry() · 93be3c2e

由 Oleg Nesterov 提交于 11月 12, 2013

We already have list_first_entry(), it makes sense to also add
list_last_entry() for consistency.  And we use both helpers in
list_for_each_*().

list: change list_for_each_entry*() to use list_*_entry() · 8120e2e5

由 Oleg Nesterov 提交于 11月 12, 2013

Now that we have list_{next,prev}_entry() we can change
list_for_each_entry*() and list_safe_reset_next() to use the new helpers
to improve the readability.

list: introduce list_next_entry() and list_prev_entry() · 008208c6

由 Oleg Nesterov 提交于 11月 12, 2013

Add two trivial helpers list_next_entry() and list_prev_entry(), they
can have a lot of users including list.h itself.  In fact the 1st one is
already defined in events/core.c and bnx2x_sp.c, so the patch simply
moves the definition to list.h.

lib/genalloc: add a helper function for DMA buffer allocation · 684f0d3d

由 Nicolin Chen 提交于 11月 12, 2013

When using pool space for DMA buffer, there might be duplicated calling of
gen_pool_alloc() and gen_pool_virt_to_phys() in each implementation.

Thus it's better to add a simple helper function, a compatible one to the
common dma_alloc_coherent(), to save some code.
