+Subject: [PATCH] tune2fs: fix tune2fs segfault when ext2fs_run_ext3_journal()
+ fails
+
+When ext2fs_run_ext3_journal() fails, tune2fs cmd will occur one
+segfault problem as follows.
+(gdb) bt
+#0  0x00007fdadad69917 in ext2fs_mmp_stop (fs=0x0) at mmp.c:405
+#1  0x0000558fa5a9365a in main (argc=<optimized out>, argv=<optimized out>) at tune2fs.c:3440
+
+misc/tune2fs.c:
+main()
+  -> ext2fs_open2(&fs)
+    -> ext2fs_mmp_start
+  ......
+  -> retval = ext2fs_run_ext3_journal(&fs)
+  -> if (retval)
+    // if ext2fs_run_ext3_journal fails, close and free fs.
+    -> ext2fs_close_free(&fs)
+    -> rc = 1
+    -> goto closefs
+  ......
+closefs:
+  -> if (rc)
+    -> ext2fs_mmp_stop(fs)     // fs has been set to NULL, boom!!
+  -> (ext2fs_close_free(&fs) ? 1 : 0); // close and free fs
+
+In main() of tune2fs cmd, if ext2fs_run_ext3_journal() fails,
+we should set rc=1 and goto closefs tag, in which will release fs
+resource.

+If some error occurs, tune2fs_main() will go to closefs tag for
+releasing resource, and it should return correct value (rc) instead
+of 0 when ext2fs_close_free(&fs) successes.

+Subject: [PATCH] tune2fs: exit directly when fs freed in ext2fs_run_ext3_journal
+
+In ext2fs_run_ext3_journal(), fs will be free and reallocate. But
+reallocating by ext2fs_open() may fail in some cases, such as device
+being offline at the same time. In these cases, goto closefs will
+cause segfault, fix it by exiting directly.
