io/fs: misleading documentation of Glob function #43537
Description
The documentation of the new fs.Glob function is a bit misleading.
When it says
Glob returns the names of all files matching pattern or nil if there is no matching file. The syntax of patterns is the same as in path.Match. The pattern may describe hierarchical names such as /usr/*/bin/ed (assuming the Separator is '/').
the last sentence is correct but refers to a specific OS file system implementation, as the file system returned by the os.DirFS function. If "/usr/*/bin/ed" is used as pattern argument to Glob, it will never return any files because the names returned by Glob are unrooted.
