From 1303e7eb2b65f5275a57b66a7bebc8bfe1b32d4f Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Thu, 22 Oct 2015 03:48:09 +0200 Subject: alpha: add special umount2 handling Only on Linux alpha __NR_oldumount is defined and a umount not umount2 syscall, but with two parameter is used. Add special handling for it and an alias for umount2() users. There was a discussion about this special handling, but it seems it was never committed upstream: http://marc.info/?l=linux-alpha&m=137455037930738&w=2 Runtime tested with qemu-alpha and a statically linked busybox binary. --- libc/sysdeps/linux/common/umount2.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'libc') diff --git a/libc/sysdeps/linux/common/umount2.c b/libc/sysdeps/linux/common/umount2.c index 08e0f3388..c86f3c80f 100644 --- a/libc/sysdeps/linux/common/umount2.c +++ b/libc/sysdeps/linux/common/umount2.c @@ -10,7 +10,12 @@ #include #if defined __UCLIBC_LINUX_SPECIFIC__ && defined __NR_umount2 -# include +#include _syscall2(int, umount2, const char *, special_file, int, flags) libc_hidden_def(umount2) #endif + +#if defined __UCLIBC_LINUX_SPECIFIC__ && defined __NR_oldumount +_syscall2(int, umount, const char *, special_file, int, flags) +strong_alias(umount,umount2) +#endif -- cgit v1.2.3
