# FS QA Test No. 005

|
|
#
|
||
|
|
# Test that a bad crc on a primary V5 superblock will fail the mount
|
||
|
|
#
|
||
|
|
# 10e6e65 xfs: be more forgiving of a v4 secondary sb w/ junk in v5 fields
|
||
|
|
# inadvertently caused primary SB CRC failures to not error out, this
|
||
|
|
# is a regression test for that fix.
