[LU-9617] RHEL-7 ext4-prealloc.patch missing error checking

• Type: Improvement
• Resolution: Fixed
• Priority: Major
• Assignee: Yang Sheng
• Reporter: Ben Evans (Inactive)

Description

For large enough stripes, ext4_mb_prealloc_table_add can fail. However nothing checks the return code, so there are 0's left in the table which can result in div 0 errors.

Patch for RHEL 6.4 and SLES11 is correct.

The patch has landed to master for 2.11 - 2.10 went out last week Also, the commit message used the original LU-3719 JIRA reference so this ticket is effectively a duplicate of LU-3719
