Subject: [PATCH v1 1/1] bitops: Move aligned_byte_mask() to wordpart.h
Date: Tue, 7 May 2024 17:01:54 +0300 [thread overview]
Message-ID: <20240507140155.197304-1-andriy.shevchenko@linux.intel.com> (raw)
The bitops.h is for bit related operations. The aligned_byte_mask()
is about byte (or part of the machine word) operations, for which
we have a separate header, move the mentioned macro to wordpart.h
to consolidate similar operations.
