commit 2f9116e4804d6332c85ee6cd362263594b2d5680 Author: Mark Johnston <[email protected]> AuthorDate: 2021-12-16 21:53:59 +0000 Commit: Mark Johnston <[email protected]> CommitDate: 2021-12-31 14:26:07 +0000 fd: Initialize more export_fd_buf fields in kern_proc_cwd_out() In particular, we need to initialize efbuf->flags, since export_vnode_to_sb() loads that field. This was mostly harmless since the flag only determines whether the output kinfo_file is packed, and KERN_PROC_CWD only ever emits a single kinfo_file anyway.
