| Subject: [PATCH] ls: restore 8.31 behavior on removed directories |
| |
| * NEWS: Mention this. |
| * src/ls.c: Do not include <sys/sycall.h> |
| (print_dir): Don't worry about whether the directory is removed. |
| * tests/ls/removed-directory.sh: Adjust to match new (i.e., old) |
| behavior. |
| |
| Upstream-Status: Backport [https://github.com/coreutils/coreutils/commit/10fcb97bd728f09d4a027eddf8ad2900f0819b0a] |
