_require_xfs_sysfs() currently assumes that all sysfs attributes reside under a device-specific subdirectory in the XFS sysfs hierarchy. It is hardcoded to use the TEST_DEV mount and expect the relative attribute path as a parameter. Not all sysfs attributes are associated with specific devices or mount points, however. Remove the hardcoded device name part of the attribute path from _require_xfs_sysfs() and let the caller construct the relative path based on the sysfs XFS root directory.

# Test the xfs log reservation mechanism for leaks. Run an fsstress workload to

# include a variety of fs operations, freeze the filesystem and verify that
