+Subject: [PATCH 1/2] libinotifytools: Include limit.h for PATH_MAX
+
+musl builds fail since the required header which defines PATH_MAX is
+missing, its perhaps included indirectly via glibc based systems

+Subject: [PATCH 2/2] libinotifytools: Bridge differences between
+ musl/glibc/kernel fnotify.h
+
+System detects to use sys/fnotify.h and then assumes glibc's definitions
+but musl has definitions of its own. perhaps portable thing would be to
+use linux/fnotify.h interface directly on linux irrespective of libc
+
+See the differences discussion here [1]
