+Subject: [PATCH 01/10] Fix build with musl
+
+--Signature=_Sat__5_Sep_2020_14_41_30_+0300_B.qpPPwu83bbA.32

+
+When musl is used instead of glibc, oprofile build fails because it
+uses glibc-specific FTW extension: FTW_ACTIONRETVAL for custom
+__delete_old_previous_sample_data return codes and FTW_STOP,
+FTW_CONTINUE for such return codes. Musl supports only POSIX ftw, so
+build fails.
+
+However, this extension is not really needed by oprofile, because
+FTW_SKIP_* are not used and {FTW_STOP,FTW_CONTINUE} can be handled
+by standard return codes {1,0} (more precisely standard defines
+{!0,0}, but in glibc FTW_STOP = 1, so I keep this value).
+
