From d0ccd0d977df62f0fe0f6c91237613b95f5d5a5f Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Fri, 24 Apr 2015 13:50:18 +0200 Subject: __ASSUME_FALLOCATE is always true on 32-bit architectures This means we can clean up the generic code a bit. The 64-bit variant still needs to support !__ASSUME_FALLOCATE for alpha. --- sysdeps/unix/sysv/linux/posix_fallocate64.c | 43 ++++++++--------------------- 1 file changed, 11 insertions(+), 32 deletions(-) (limited to 'sysdeps/unix/sysv/linux/posix_fallocate64.c') diff --git a/sysdeps/unix/sysv/linux/posix_fallocate64.c b/sysdeps/unix/sysv/linux/posix_fallocate64.c index 9545459013..771e59cb0b 100644 --- a/sysdeps/unix/sysv/linux/posix_fallocate64.c +++ b/sysdeps/unix/sysv/linux/posix_fallocate64.c @@ -16,7 +16,6 @@ . */ #include -#include #include extern int __posix_fallocate64_l64 (int fd, __off64_t offset, __off64_t len); @@ -24,40 +23,20 @@ extern int __posix_fallocate64_l64 (int fd, __off64_t offset, __off64_t len); #include #undef __posix_fallocate64_l64 -#if !defined __ASSUME_FALLOCATE && defined __NR_fallocate -/* Defined in posix_fallocate.c. */ -extern int __have_fallocate attribute_hidden; -#endif - - /* Reserve storage for the data of the file associated with FD. */ int __posix_fallocate64_l64 (int fd, __off64_t offset, __off64_t len) { -#ifdef __NR_fallocate -# ifndef __ASSUME_FALLOCATE - if (__glibc_likely (__have_fallocate >= 0)) -# endif - { - INTERNAL_SYSCALL_DECL (err); - int res = INTERNAL_SYSCALL (fallocate, err, 6, fd, 0, - __LONG_LONG_PAIR ((long int) (offset >> 32), - (long int) offset), - __LONG_LONG_PAIR ((long int) (len >> 32), - (long int) len)); - - if (!
