Subject: [PATCH v2 11/14] perf expr: Tidy hashmap dependency
Date: Wed,  9 Nov 2022 10:49:11 -0800	[thread overview]
Message-ID: <20221109184914.1357295-12-irogers@google.com> (raw)
In-Reply-To: <20221109184914.1357295-1-irogers@google.com>

hashmap.h comes from libbpf but isn't installed with its
headers. Always use the header file of the code in util. Change the
hashmap.h dependency in expr.h to a forward declaration, add the
necessary header file includes in the C files.
