This is needed with ACPI and\n one almost-clone chip which uses a special wakeup-only alarm. (That\u0027s\n the RTC used on Footbridge boards, FWIW, which don\u0027t do PM in Linux.)\n\nA separate patch implements those hooks for ACPI platforms, so that rtc_cmos\ncan issue system wakeup events (and its sysfs \"wakealarm\" attribute works on\nat least some systems).\n\nSigned-off-by: David Brownell \u003cdbrownell@users.sourceforge.net\u003e\nCc: Alessandro Zummo \u003ca.zummo@towertech.it\u003e\nCc: Len Brown \u003clenb@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "cd9662094edf4173e87f0452e57e4eacc228f8ff", "tree": "819d487aad05c7e61531bd25e3e7a0d4c08c6616", "parents": [ "7d9f99eccc8f94ace31030a2a7ff73cf5f8c12a0" ], "author": { "name": "David Brownell", "email": "david-b@pacbell.net", "time": "Tue May 08 00:33:40 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue May 08 11:15:18 2007 -0700" }, "message": "rtc: remove rest of class_device\n\nFinish converting the RTC framework so it no longer uses class_device.\n\nSigned-off-by: David Brownell \u003cdbrownell@users.sourceforge.net\u003e\nAcked-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\nAcked-By: Alessandro Zummo \u003ca.zummo@towertech.it\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "ab6a2d70d18edc7a716ef3127b9e13382faec98c", "tree": "6de624dfcbd0181e54e21f1730d2a52ae9822c47", "parents": [ "5726fb2012f0d96153113ddb7f988a0daea587ce" ], "author": { "name": "David Brownell", "email": "david-b@pacbell.net", "time": "Tue May 08 00:33:30 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue May 08 11:15:18 2007 -0700" }, "message": "rtc: rtc interfaces don\u0027t use class_device\n\nThis patch removes class_device from the programming interface that the RTC\nframework exposes to the rest of the kernel.

They assume a role that should be the responsibility of\ninfrastructure code: creating device nodes.\n\nThe \"modprobe\" step in hotplugging relies on drivers to have split those\nroles into different modules. The lack of this split causes the problems.\nWhen a driver creates nodes for devices that don\u0027t exist (sending a hotplug\nevent), then exits (aborting one modprobe) before the \"modprobe $MODALIAS\"\nstep completes (by failing, since it\u0027s in the middle of a modprobe), the\nresult can be an endless loop of modprobe invocations ... badness.\n\nThis fix uses the newish per-device flag controlling issuance of \"add\"\nevents. (A previous version of this patch used a per-device \"driver can\nhotplug\" flag, which only scrubbed $MODALIAS from the environment rather\nthan suppressing the entire hotplug event.) It also shrinks that flag to\none bit, saving a word in \"struct device\".\n\nSo the net of this patch is removing some nasty failures with legacy\ndrivers, while retaining hotplug capability for the majority of platform\ndrivers.\n\nSigned-off-by: David Brownell \u003cdbrownell@users.sourceforge.net\u003e\nCc: Greg KH \u003cgregkh@suse.de\u003e\nCc: Andres Salomon \u003cdilinger@debian.org\u003e\nCc: Dominik Brodowski \u003clinux@dominikbrodowski.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "6272e2667965dfb5b59199f462cd0f001fb304a6", "tree": "a14a4537dcd7af09863cc3a1c19a3efe386d67ab", "parents": [ "039b6b3ed84e45a6f8316358dd2bfdc83d59fc45" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Tue May 08 00:29:21 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue May 08 11:15:09 2007 -0700" }, "message": "cleanup compat ioctl handling\n\nMerge all compat ioctl handling into compat_ioctl.c instead of splitting it\nover compat.c and compat_ioctl.c.

From the user\u0027s view there are lots of different filesystem\ntypes. The user is not even much concerned if the filesystem is fuse based\nor not. So there\u0027s a conflict of interest in how this should be\nrepresented in fstab, mtab and /proc/mounts.\n\nThe current scheme is to encode the real filesystem type in the mount\nsource. So an sshfs mount looks like this:\n\n sshfs#user@server:/ /mnt/server fuse rw,nosuid,nodev,...\n\nThis url-ish syntax works OK for sshfs and similar filesystems. However\nfor block device based filesystems (ntfs-3g, zfs) it doesn\u0027t work, since\nthe kernel expects the mount source to be a real device name.\n\nA possibly better scheme would be to encode the real type in the type\nfield as \"type.subtype\".
