      Failure, when the number of pages is mentioned in terms of total size, which is less than 1M:

      [root@vbox tests]# lctl set_param osc.lustre-OST0000-osc-ffff9fd875168800.max_pages_per_rpc=0.5M
error: set_param: setting /sys/fs/lustre/osc/lustre-OST0000-osc-ffff9fd875168800/max_pages_per_rpc=0.5M: Numerical result out of range
error: set_param: setting 'osc/lustre-OST0000-osc-ffff9fd875168800/max_pages_per_rpc'='0.5M': Numerical result out of range

      Working correctly, when the number of pages is given such that the total size is less than 1M:

      [root@vbox lustre-release]# getconf PAGE_SIZE
4096
[root@vbox tests]# lctl set_param osc.lustre-OST0000-osc-ffff9fd875168800.max_pages_per_rpc=128
osc.lustre-OST0000-osc-ffff9fd875168800.max_pages_per_rpc=128
