+Subject: btrfs-progs: mkfs/rootdir: Don't follow symbolic link when calcuating
+ size
+From: Qu Wenruo <wqu@suse.com>
+X-Patchwork-Id: 10312225
+Message-Id: <20180328063909.937-1-wqu@suse.com>
+To: linux-btrfs@vger.kernel.org

+
+[BUG]
+If we have a symbolic link in rootdir pointing to non-existing location,
+mkfs.btrfs --rootdir will just fail:
+------
+$ mkfs.btrfs  -f --rootdir /tmp/rootdir/ /dev/data/btrfs
+btrfs-progs v4.15.1
+See http://btrfs.wiki.kernel.org for more information.
+
+ERROR: ftw subdir walk of /tmp/rootdir/ failed: No such file or directory
+------
+
+[CAUSE]
+Commit 599a0abed564 ("btrfs-progs: mkfs/rootdir: Use over-reserve method
+to make size estimate easier") add extra ftw walk to estimate the
+filesystem size.
+
+Such default ftw walk will follow symbolic link and gives ENOENT error.
+
+[FIX]
+Use nftw() to specify FTW_PHYS so we won't follow symbolic link for size
+calculation.
