[PATCH 2/3] generic/382: Fix test when report uses /etc/passwd

[Date Prev] [Date Next] [Thread Prev] [Thread Next] [Date Index] [Thread Index]



On older kernels xfs_quota uses /etc/passwd to report quota entries. In
such case all-zero lines disturb its output and the test fails. Fix the
problem by ignoring all-zero lines in quota report.
