Subject: [PATCH] copy: copy_file_range: handle ENOENT for CIFS
|
|
|
|
* src/copy.c (sparse_copy): Fallback to standard copy upon ENOENT,
|
|
which was seen intermittently across CIFS file systems.
|
|
* NEWS: Mention the bug fix, though qualify it as an "issue"
|
|
rather than a bug, as coreutils is likely only highlighting
|
|
a CIFS bug in this case.

** Bug fixes
|
|
+ cp, mv, and install now handle ENOENT failures across CIFS file systems,
|
|
+ falling back from copy_file_range to a better supported standard copy.
|
|
+ [issue introduced in coreutils-9.0]
|
|
+
|
|
stty now wraps output appropriately for the terminal width.
|
|
Previously it may have output 1 character too wide for certain widths.
