From 6c63e2d8dfb1dd8b6383b4758080841a0fad37a4 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Mon, 11 Apr 2016 15:04:59 -0300 Subject: Consolidate fallocate{64} implementations This patch consolidates all the fallocate{64} implementation for Linux in only one (sysdeps/unix/sysv/linux/fallocate{64}.c). It also removes the syscall from the auto-generation using assembly macros. The new macro SYSCALL_LL{64} is used to handle the offset argument. Checked on x86_64, x32, i386, aarch64, and ppc64le. * sysdeps/unix/sysv/linux/Makefile (test): Add tst-fallocate and tst-fallocate64. * sysdeps/unix/sysv/linux/tst-fallocate.c: New file. * sysdeps/unix/sysv/linux/tst-fallocate64.c: Likewise. * sysdeps/unix/sysv/linux/tst-fallocate-common.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/fallocate.c: Remove file. * sysdeps/unix/sysv/linux/mips/mips64/n32/fallocate64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/fallocate.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/fallocate64.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/fallocate.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/fallocate64.c: Likewise. * sysdeps/unix/sysv/linux/fallocate.c (fallocate): Use SYSCALL_LL macro on offset argument. * sysdeps/unix/sysv/linux/fallocate64.c (fallocate64): Use SYSCALL_LL64 on offset argument. * test-skeleton.c (FAIL_RET): Add macro. (FAIL_EXIT): Likewise. (FAIL_EXIT1): Likewise. (_FAIL): Likewise. --- sysdeps/unix/sysv/linux/fallocate.c | 11 +++-------- 1 file changed, 3 insertions(+), 8 deletions(-) (limited to 'sysdeps/unix/sysv/linux/fallocate.c') diff --git a/sysdeps/unix/sysv/linux/fallocate.c b/sysdeps/unix/sysv/linux/fallocate.c index 6a58a5f50a..a38e9a6a98 100644 --- a/sysdeps/unix/sysv/linux/fallocate.c +++ b/sysdeps/unix/sysv/linux/fallocate.c @@ -19,17 +19,12 @@ #include #include - +#ifndef __OFF_T_MATCHES_OFF64_T /* Reserve storage for the data of the file associated with FD. */ int fallocate (int fd, int mode, __off_t offset, __off_t len) { -#ifdef __NR_fallocate return SYSCALL_CANCEL (fallocate, fd, mode, - __LONG_LONG_PAIR (offset >> 31, offset), - __LONG_LONG_PAIR (len >> 31, len)); -#else - __set_errno (ENOSYS); - return -1; -#endif + SYSCALL_LL (offset), SYSCALL_LL (len)); } +#endif -- cgit v1.2.3-70-g09d2
