Start making the rtc-cmos alarm act more like a oneshot alarm by disabling that alarm after its IRQ fires. (ACPI hooks are also needed.) The Linux RTC framework has previously been a bit vague in this area, but any other behavior is problematic and not very portable. RTCs with full YYYY-MM-DD HH:MM[:SS] alarms won't have a problem here. Only ones with partial match criteria, with the most visible example being the PC RTC, get confused. (Because the criteria will match repeatedly.) Update comments relating to that oneshot behavior and timezone handling. (Timezones are another issue that's mostly visible with rtc-cmos. That's because PCs often dual-boot MS-Windows, which likes its RTC to match local wall-clock time instead of UTC.) Signed-off-by:

This adds a basic ds1302 RTC driver, which is basically a cleanup and move of the in-tree SH SecureEdge5410 code (which is currently located in arch/sh/board/snapgear/rtc.c) to drivers/rtc. This aims to be a building block that the M32R and CRIS code can be worked on top of, so we can get rid of drivers/char/ds1302.c and arch/cris/arch-v10/drivers/ds1302.c respectively, though more work is needed for this.

This makes rtc-cmos export its NVRAM, like several other RTC drivers. It still works within the limits of the current CMOS_READ/CMOS_WRITE calls, which don't understand how to access multiple register banks. The primary impact of that limitation is that Linux can't access the uppermost 128 bytes of NVRAM on many systems. Note that this isn't aiming to be a drop-in replacement for the legacy /dev/nvram support. (Presumably that has real users, and isn't just getting carried forward automatically?) Userspace handles more work: - When userspace code updates NVRAM, that will need to include updating any platform-specific checksums that may apply. - No /proc/driver/nvram file will parse and display NVRAM data according to whichever boot firmware your board expects. Also minor pnp-related updates: update a comment, remove dead code. Signed-off-by:

The rtc-pcf8583 driver is using the I2C_M_NOSTART flag but shouldn't. This flag is only meant for broken chips and the PCF8583 RTC chip is not one of these. Signed-off-by:

Libfuse basically creates a new thread for each new request. This is fine for synchronous requests, which are naturally limited. However background requests (especially writepage) can cause a thread creation storm. To avoid this, limit the number of background requests available to userspace. This is done by introducing another queue for background requests, and a counter for the number of "active" requests, which are currently available for userspace. Signed-off-by:

Jeff Moyer pointed out that a mount; umount loop of ecryptfs, with the same cipher & other mount options, created a new ecryptfs_key_tfm_cache item each time, and the cache could grow quite large this way. Looking at this with mhalcrow, we saw that ecryptfs_parse_options() unconditionally called ecryptfs_add_new_key_tfm(), which is what was adding these items. Refactor ecryptfs_get_tfm_and_mutex_for_cipher_name() to create a new helper function, ecryptfs_tfm_exists(), which checks for the cipher on the cached key_tfm_list, and sets a pointer to it if it exists. This can then be called from ecryptfs_parse_options(), and new key_tfm's can be added only when a cached one is not found. With list locking changes suggested by akpm. Signed-off-by:

ecryptfs_debug really should not be a mount option; it is not per-mount, but rather sets a global "ecryptfs_verbosity" variable which affects all mounted filesysytems. It's already settable as a module load option, I think we can leave it at that. Also, if set, since secret values come out in debug messages, kick things off with a stern warning. Signed-off-by:

Eric Sandeen authored
Change ecryptfs_show_options to reflect the actual mount options in use. Note that this does away with the "dir=" output, which is not a valid mount option and appears to be unused. Mount options such as "ecryptfs_verbose" and "ecryptfs_xattr_metadata" are somewhat indeterminate for a given fs, but in any case the reported mount options can be used in a new mount command to get the same behavior.

The ser_gigaset ISDN driver was using a mutex in its close() method for waiting for other running ldisc methods to finish. That's what completions are for. Incidentally, this also avoids a spurious "BUG: lock held at task exit time" message when the driver's userspace daemon daemonizes itself. Signed-off-by:

Add basic suspend/resume support to the usb_gigaset driver for the Siemens Gigaset M105 USB DECT adapter. Only the USB aspects are handled so far; the ISDN subsystem is not notified in any way, for lack of information about how to do that. The driver does not check for active connections before suspending. They will be dropped when the device loses USB power. Signed-off-by:
