package/oprofile/0001-musl.patch

   1 Remove non-Posix use of FTW_ACTIONRETVAL
   2
   3 The musl implementation of nftw doesn't support the glibc extension
   4 FTW_ACTIONRETVAL. Since none of the features of FTW_ACTIONRETVAL are
   5 used here, just use the normal nftw return value.

  12 Removed unneeded patch for libop/op_events.c.

  14 Because openwrt removed the oprofile package from their repo last week
  15 https://github.com/openwrt-mirror/openwrt/commit/aaf46a8524e138e1673a398e8d2dd9357405b313#diff-fe14456f94abf436d997e2c01c10f3bd
  16 I decided to put this patch into the buildroot repo instead of adding
  17 _PATCH to oprofile.mk
