If a workaround was really necessary I'd agree with Jonathan. But it looks like a workaround to fix up st_size is not necessary, because both Krusader and ls (just two examples I could easily find) work without changing st_size. Note that they use a different way to check whether the current file is a symlink, not sure if that makes the difference though. https://quickgit.kde.org/?p=krusader.git&a=blob&h=932340774d439b1ea770204903c1f8c431dc86db&hb=f1660b241d195a31a904a1706fb8022b99e4c709&f=krusader%2FVFS%2Fnormal_vfs.cpp http://git.savannah.gnu.org/cgit/coreutils.git/tree/src/ls.c - Andreas Hartmetz On Oct. 25, 2016, 2:51 p.m., taro yamada wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
