From a7d82369dcae0d666e4ef63eef3236f2f7ac7d94 Mon Sep 17 00:00:00 2001 From: Shin'ichiro Kawasaki Date: Tue, 14 Jan 2025 12:48:31 +0900 Subject: [PATCH] fsx: fix compile error for preadv2() Commit d6b9d8eff076 ("fsx: add support for RWF_DONTCACHE") introduced preadv2() calls in ltp/fsx.c. However, sys/uio.h is not included to the source file, which causes compile errors with the gcc option -Werror-implicit-function-declaration: fsx.c: In function 'test_dontcache_io': fsx.c:1956:15: error: implicit declaration of function 'preadv2'; did you mean 'pread64'? [-Wimplicit-function-declaration] 1956 | ret = preadv2(fd, &iov, 1, 0, RWF_DONTCACHE); | ^~~~~~~ | pread64 fsx.c: In function 'fsx_rw': fsx.c:2836:31: error: implicit declaration of function 'pwritev2'; did you mean 'pwrite64'? [-Wimplicit-function-declaration] 2836 | ret = pwritev2(fd, &iov, 1, offset, flags); | ^~~~~~~~ | pwrite64 To fix it, add the include directive.
