+Subject: [PATCH] librdmacm: Allow librspreload version script entries the libc
+ lacks
+
+librspreload.map exports fcntl, fcntl64, sendfile and sendfile64, but
+which of them preload.c ends up defining depends on the libc. On musl
+there are no LFS64 symbols, so the fcntl64() and sendfile64() wrappers
+are not built, while on glibc with _FILE_OFFSET_BITS=64 the fcntl() and
+sendfile() wrappers are emitted as fcntl64 and sendfile64. Linkers that
+check the version script, like lld, then fail, e.g. on musl:
+
+  error: version script assignment of 'global' to symbol 'fcntl64' failed: symbol not defined
+  error: version script assignment of 'global' to symbol 'sendfile64' failed: symbol not defined
+
+Pass --undefined-version for the preload module when the linker
+supports it, so whichever of these names are defined get exported.
+
+Upstream-Status: Submitted [https://github.com/linux-rdma/rdma-core/pull/1853]
