  "message": "hugetlb: new sysfs interface\n\nProvide new hugepages user APIs that are more suited to multiple hstates\nin sysfs.  There is a new directory, /sys/kernel/hugepages.  Underneath\nthat directory there will be a directory per-supported hugepage size,\ne.g.:\n\n/sys/kernel/hugepages/hugepages-64kB\n/sys/kernel/hugepages/hugepages-16384kB\n/sys/kernel/hugepages/hugepages-16777216kB\n\ncorresponding to 64k, 16m and 16g respectively.  Within each\nhugepages-size directory there are a number of files, corresponding to the\ntracked counters in the hstate, e.g.:\n\n/sys/kernel/hugepages/hugepages-64/nr_hugepages\n/sys/kernel/hugepages/hugepages-64/nr_overcommit_hugepages\n/sys/kernel/hugepages/hugepages-64/free_hugepages\n/sys/kernel/hugepages/hugepages-64/resv_hugepages\n/sys/kernel/hugepages/hugepages-64/surplus_hugepages\n\nOf these files, the first two are read-write and the latter three are\nread-only.  The size of the hugepage being manipulated is trivially\ndeducible from the enclosing directory and is always expressed in kB (to\nmatch meminfo).\n\n[dave@linux.vnet.ibm.com: fix build]\n[nacc@us.ibm.com: hugetlb: hang off of /sys/kernel/mm rather than /sys/kernel]\n[nacc@us.ibm.com: hugetlb: remove CONFIG_SYSFS dependency]\nAcked-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\nSigned-off-by: Nishanth Aravamudan \u003cnacc@us.ibm.com\u003e\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Dave Hansen \u003cdave@linux.vnet.ibm.com\u003e\nSigned-off-by: Nishanth Aravamudan \u003cnacc@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
