Subject[PATCH 4/4] docs: sphinx: Add support :nosymbols: to exclude specific symbols
Date
Add :nosymbols: so that documentation of symbols can be organized in the
final output of makedocs. For example, files that define a large number
of symbols may want to categorize their symbols. Another example is
SGX, which introduces a uapi header that defines structs for ioctls and
for a new vDSO function[1]. Ideally, the documentation for the vDSO
struct will be placed into a different section.
