If the previous thing cat'ing $debugfs/rd left the FIFO full, then
subsequent open could deadlock in rd_write() (because open is blocked,

it is generally a good idea to clear out old data from the FIFO.

Further details:
After logging into spinchat the issue does not occur straight away. It takes a
bit, use all buttons a while.
This seems to suggest that the issue is related to a memory buffer that
drmm_universal_plane_alloc() already registers drm_plane_cleanup() as
managed release action via drmm_add_action_or_reset(). Hence,
drm_plane_cleanup() should not be set as drm_plane_funcs.destroy hook.

Since the user can control the arguments of the ioctl() from the user
space, under special arguments that may result in a divide-by-zero bug.
If the user provides an improper 'pixclock' value that makes the argumet
of i740_calc_vclk() less than 'I740_RFREQ_FIX', it will cause a
divide-by-zero bug
Since the user can control the arguments of the ioctl() from the user

in:

Currently we are assuming a one to one mapping between dmabuf and handle
when releasing GEM handles.
But that is not always true, since we would create extra handles for the
GEM obj in cases like gem_open() and getfb{,2}().

Purpose of these patches is to add a new dma-buf heap: linaro,secure-heap
Linaro OPTEE OS Secure Data Path feature is relying on a reserved memory
defined at Linux Kernel level and OPTEE OS level.
>From Linux Kernel side, heap management is using dma-buf heaps interface.

The double `by' is duplicated in the comment, remove one.

This patch provides infrastructure for deferring buffer frees.
This is a feature ION provided which when used with some form
of a page pool, provides a nice performance boost in an
allocation microbenchmark. The reason it helps is it allows the
page-zeroing to be done out of
add Linaro secure heap bindings: linaro,secure-heap
use genalloc to allocate/free buffer from buffer pool.
buffer pool info is from dts.
use sg_table instore the allocated memory info, the length of sg_table is 1.
implement secure_heap_buf_ops to implement buffer share in difference device:
1.

This patch adds a simple shrinker controlled page pool to the
dmabuf heaps subsystem.
This replaces the use of the networking page_pool, over concerns
that the lack of a shrinker for that implementation may cause
additional low-memory kills
