Theodore Ts'o 503358ae01 ext4: avoid divide by zero when trying to mount a corrupted file system ... If s_log_groups_per_flex is greater than 31, then groups_per_flex will will overflow and cause a divide by zero error. This can cause kernel BUG if such a file system is mounted. Thanks to Nageswara R Sastry for analyzing the failure and providing an initial patch. http://bugzilla.kernel.org/show_bug.cgi?id=14287 Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Cc: stable@kernel.org		2009-11-23 07:24:46 -05:00
