Subject: [PATCH] cifs: Fix separator when building path from dentry
Git-commit: c988de29ca161823db6a7125e803d597ef75b49c
Patch-mainline: v4.20-rc6
References: bsc#1051510, bsc#1144333
Make sure to use the CIFS_DIR_SEP(cifs_sb) as path separator for
prefixpath too. Fixes a bug with smb1 UNIX extensions.
Fixes: a6b5058fafdf ("fs/cifs: make share unaccessible at root level mountable")
