idletime: maintain cpuset over lifetime of idle thread (2015-01-28 14:47:48
-0700)
----------------------------------------------------------------
Felipe Franciosi (1):
Fixing typo
Jens Axboe (3):
gettime: if setaffinity fails, print the errno error
gettime: initialize cpusets properly
idletime: maintain cpuset over lifetime of idle thread
Justin Eno (1):
Better accommodate random writes larger than blockalign
Vasily Tarasov (1):
dedupe_percentage should work even if compress_percentage is not set
