This will drastically speed up the bandwidth\ncomputations.\n\nIn addition, it eliminates a theoretical bug. An isochronous endpoint\nmay have bandwidth reserved even at times when it has no transfers\nlisted in the schedule. The table will keep track of the reserved\nbandwidth, whereas adding up entries in the schedule would miss it.\n\nAs a corollary, we can keep bandwidth reserved for endpoints even\nwhen they aren\u0027t in active use. Eventually the bandwidth will be\nreserved when a new alternate setting is installed; for now the\nendpoint\u0027s reservation takes place when its first URB is submitted.\n\nA drawback of this approach is that transfers with an interval larger\nthan 64 microframes will have to be charged for bandwidth as though\nthe interval was 64. In practice this shouldn\u0027t matter much;\ntransfers with longer intervals tend to be rather short anyway (things\nlike hubs or HID devices).\n\nAnother minor drawback is that we will keep track of two different\nperiod and phase values: the actual ones and the ones used for\nbandwidth allocation (which are limited to 64). This adds only a\nsmall amount of overhead: 3 bytes for each endpoint.\n\nThe patch also adds a new debugfs file named \"bandwidth\" to display\nthe information stored in the new table.\n\nSigned-off-by: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n" }, { "commit": "ffa0248e643175cea3887c7058916af53104d8e5", "tree": "3b6604905aaffc4ab60037d265c4f06f1d144f8a", "parents": [ "91a99b5e78849db90dc2f5e8dfa034af43bdb760" ], "author": { "name": "Alan Stern", "email": "stern@rowland.harvard.edu", "time": "Fri Oct 11 11:29:03 2013 -0400" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Fri Oct 11 16:40:27 2013 -0700" }, "message": "USB: EHCI: create a \"periodic schedule info\" struct\n\nThis patch begins the process of unifying the scheduling parameters\nthat ehci-hcd uses for interrupt and isochronous transfers.

This is ok as long as we commit another transaction\nat some point in the future, but if you abort or something else goes wrong you\ncan end up in this weird state because the recovery stuff says that the tree log\nshould have a generation+1 of the super generation, which won\u0027t be the case of\nthe transaction that was started for recovery. Fix this by removing the check\nand _always_ zero out the log portion of the super when we commit a transaction.\nThis fixes the transid verify issues I was seeing with my force errors tests.\nThanks,\n\nSigned-off-by: Josef Bacik \u003cjbacik@fusionio.com\u003e\n" }, { "commit": "19e49834d22c2271ed1f4a03aaa4b74986447fb4", "tree": "08ec1c521fc151b78b8d1c654d940b1e279edbe4", "parents": [ "15c83d26e16d19522ebba2a8c38b77fbe64e6ca3" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Oct 04 12:54:11 2013 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Oct 04 12:54:11 2013 -0700" }, "message": "selinux: remove \u0027flags\u0027 parameter from inode_has_perm\n\nEvery single user passes in \u00270\u0027.
