-Subject: [PATCH] lib/crc32: prefix public functions
|
|
|
|
-
|
|
|
|
-Make the publicly-visible crc32 library functions prefixed by ul_, such
|
|
|
|
-as crc32() -> ul_crc32().
|
|
|
|
-This is because it clashes with the crc32() function from zlib.
|
|
|
|
-For newer versions of glib (2.50+) zlib and libblkid are required
|
|
|
|
-dependencies and otherwise results in build failure when building
|
|
|
|
-statically.
