 preshrink is nonzero when the nr_inodes > inode-max and the
 system needs to prune the inode list instead of allocating
 more.

+==============================================================
+
+overflowgid & overflowuid:
+
+Some filesystems only support 16-bit UIDs and GIDs, although in Linux
+UIDs and GIDs are 32 bits. When one of these filesystems is mounted
+with writes enabled, any UID or GID that would exceed 65535 is translated
+to a fixed value before being written to disk.
+
+These sysctls allow you to change the value of the fixed UID and GID.
+The default is 65534.
