+Subject: [PATCH] resize2fs: Make minimum size estimates more reliable for
+ mounted fs
+References: bsc#1154295
+
+Currently, the estimate of minimum filesystem size is using free blocks
+counter in the superblock. The counter generally doesn't get updated
+while the filesystem is mounted and thus the estimate is very unreliable
+for a mounted filesystem. For some usecases such as automated
+partitioning proposal to the user it is desirable that the estimate of
+minimum filesystem size is reasonably accurate even for a mounted
+filesystem. So use group descriptor counters of free blocks for the
+estimate of minimum filesystem size. These get updated together with
+block being allocated and so the resulting estimate is more accurate.
