Fix ksys_sync_file_range() to avoid fdput() after a failed fdget().
fdput() doesn't do fput() on this file since FDPUT_FPUT isn't set
in fd.flags. Fix it anyway since failed fdget() doesn't require
a fdput().
This was introdcued in a commit to add sync_file_range() helper.
Er... What's the point microoptimizing the slow path here?
PS: I'm not saying the patch is incorrect, but Fixes: is IMO over the
top. And looking at that thing,
{
struct fd f = fdget(fd);
int ret;
if (unlikely(!f.file))
return -EBADF;
ret = sync_file_range(f.file, offset, nbytes, flags);
fdput(f);
return ret;
}
might be cleaner, but that's a matter of taste...
This makes it easier to read.
Yes it does. I will make the changes and send v2.
