From c57bf7c15ba179168d01f7c6acde7ecbf5dd9cd8 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Sun, 22 Apr 2018 17:55:11 -0300 Subject: Consolidate Linux readahead implementation This patch consolidate Linux readahead implementation on generic sysdeps/unix/sysv/linux/readahead.c one. The changes are: - Assume __NR_readahead existence with current minimum kernel of 3.2 for all architectures. - Use INLINE_SYSCALL_CALL, __ALIGNMENT_ARG, and SYSCALL_LL64 to pass the 64 bit offset. This allows architectures with different abis to use the same implementation. - Remove arch-specific readahead implementations. Checked on x86_64-linux-gnu and i686-linux-gnu. * sysdeps/unix/sysv/linux/arm/readahead.c: Remove file. * sysdeps/unix/sysv/linux/mips/mips32/readahead.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/syscalls.list (readahead): Remove. * sysdeps/unix/sysv/linux/mips/mips64/n64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/readahead.c (__readahead): Assume __NR_readahead existence, and use INLINE_SYSCALL_CALL, __ALIGNMENT_ARG, and SYSCALL_LL64. --- sysdeps/unix/sysv/linux/wordsize-64/syscalls.list | 1 - 1 file changed, 1 deletion(-) (limited to 'sysdeps/unix/sysv/linux/wordsize-64') diff --git a/sysdeps/unix/sysv/linux/wordsize-64/syscalls.list b/sysdeps/unix/sysv/linux/wordsize-64/syscalls.list index 4bb7ebfacb..5de6ec823a 100644 --- a/sysdeps/unix/sysv/linux/wordsize-64/syscalls.list +++ b/sysdeps/unix/sysv/linux/wordsize-64/syscalls.list @@ -2,7 +2,6 @@ fstatfs - fstatfs i:ip __fstatfs fstatfs fstatfs64 __fstatfs64 statfs - statfs i:sp __statfs statfs statfs64 -readahead - readahead i:iii __readahead readahead sendfile - sendfile i:iipi sendfile sendfile64 prlimit EXTRA prlimit64 i:iipp prlimit prlimit64 -- cgit 1.4.1
