From ece4fa9152ea37c7ebd158af330e3b20e33cf385 Mon Sep 17 00:00:00 2001 From: Maxim Levitsky Date: Wed, 11 Nov 2020 17:39:12 +0200 Subject: [PATCH] file-posix: allow -EBUSY errors during write zeros on raw block devices On Linux, fallocate(fd, FALLOC_FL_PUNCH_HOLE) when it is used on a block device, without O_DIRECT can return -EBUSY if it races with another write to the same page. Since this is rare and discard is not a critical operation, ignore this error Signed-off-by: Maxim Levitsky Message-Id: <20201111153913.41840-2-mlevitsk@redhat.com> Signed-off-by: Kevin Wolf --- block/file-posix.c | 1 + 1 file changed, 1 insertion(+) diff --git a/block/file-posix.c b/block/file-posix.c index c63926d592..d5fd1dbcd2 100644 --- a/block/file-posix.c +++ b/block/file-posix.c @@ -1698,6 +1698,7 @@ static int handle_aiocb_write_zeroes_unmap(void *opaque) switch (ret) { case -ENOTSUP: case -EINVAL: + case -EBUSY: break; default: return ret; -- 2.11.0
