Subject: [PATCH] quotaio_xfs: Fix error handling in xfs_read_dquot()
|
|
|
|
When quotactl(2) fails, xfs_read_dquot() will happily return zero-filled
|
|
structure. This is fine when the user structure does not exist but it is
|
|
wrong when there's other error (like EACCESS). Fix the error handling.
