From 723aa3b0c2eed070f7eeadd2ce2d87f46da6d0f8 Mon Sep 17 00:00:00 2001 From: Etienne Dechamps Date: Mon, 16 Jul 2012 17:04:05 +0200 Subject: [PATCH] When checking for symbol exports, try compiling. This patch adds a new autoconf function: SPL_LINUX_TRY_COMPILE_SYMBOL. This new function does the following: - Call LINUX_TRY_COMPILE with the specified parameters. - If unsuccessful, return false. - If successful and we're configuring with --enable-linux-builtin, return true. - Else, call CHECK_SYMBOL_EXPORT with the specified parameters and return the result. All calls to CHECK_SYMBOL_EXPORT are converted to LINUX_TRY_COMPILE_SYMBOL so that the tests work even when configuring for builtin on a kernel which doesn't have loadable module support, or hasn't been built yet. The only exception are: - AC_GET_VMALLOC_INFO, because we don't even have a public header to include in the test case, but that's okay considering this symbol can be ignored just fine. - SPL_AC_DEVICE_CREATE, which is legacy API for 2.6.18 kernels. Since kernels this old are no longer supported it should arguably just be removed entirely from the build system. Note that we're also checking for the correct prototype with an actual call, which was not the case with CHECK_SYMBOL_EXPORT. However, for "complicated" test cases like with multiple symbol versions (e.g. vfs_fsync), we stick with the original behavior and only check for the function's existence.
