Subject: Namespace lttng/align.h as lttng/ust-align.h
X-Git-Tag: v2.13.0-rc1~250
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=3d3a2bb817fcab854dc3a90dd80e073869bbccb4;p=lttng-ust.git

Namespace lttng/align.h as lttng/ust-align.h

Since the 'lttng/' header directory is shared between ust and tools,
namespace this common name header with 'ust-' to match the same pattern
as the other files.
