2012-07-16olpc-battery: Add VOLTAGE_MAX_DESIGN propertyRichard A. Smith1-0/+56
upowerd wants to compute the energy in the battery by looking at this property. If it's not present then it falls back on using the reported voltage of the battery at time upowerd loads. That's close but also means that every time you boot you get a slightly different energy capacity. Adding the VOLTAGE_MAX_DESIGN property allows upowerd to compute the same energy every time.

2012-07-13power_supply: Add min/max alert properties for CAPACITY, TEMP, TEMP_AMBIENTRamakrishna Pallala3-0/+18
Minimum and maximum alerts on power supply properties will help or allow the user space to "proactively" create policies like connect/disconnect charger or stop/start the user apps based on capacity or temperature parameters. These parameters can be used to avoid unnecessary polling from user space and even from kernel space if the underlying HW can support INT triggers (ex: max17042/47). This patch adds the following power supply alert type properties: CAPACITY_ALERT_MIN CAPACITY_ALERT_MAX TEMP_ALERT_MIN TEMP_ALERT_MAX TEMP_AMBIENT_ALERT_MIN TEMP_AMBIENT_ALERT_MAX Signed-off-by: Ramakrishna Pallala <ramakrishna.pallala@intel.com> Signed-off-by: Anton Vorontsov <anton.vorontsov@linaro.org>

2012-06-19sbs-battery: Don't trigger false supply_changed eventNikolaus Voss1-1/+1
power_supply_changed() events are triggerd based on the return value of a get_property() call. However the property TECHNOLOGY is hard-coded to LION in this driver, thus always succeeds. So, with the battery removed, this triggers a false battery present uevent. This uevent triggers a new query via power_supply_uevent() which again starts to query all known properties and thus leads to an infinite loop of battery present/not-present uevents. This patch skips the battery presence detection for the hard-coded property TECHNOLOGY.

2012-06-19power_supply: Add constant charge_current and charge_voltage propertiesRamakrishna Pallala3-0/+10
Constant Charge Current(CC) is charging parameter which limit the maximum current which can be pumped into the battery during charge cycle. Constant Charge Voltage(CV) is also charging parameter which limit the maximum voltage that battery can reach during charge cycle. It is very common practice that at low or high temperatures we do not charge the batteries upto it's fullest charge voltage to avoid battery and user safety issues. These sysfs properties will be useful for debug and to implement certain user space policies like "Charging limited due to OverTemp".

2012-06-16tile: fix bug in get_user() for 4-byte valuesChris Metcalf1-1/+1
The definition of 32-bit values in the 64-bit tilegx architecture is that they should be sign-extended regardless of whether they are considered signed or unsigned by the compiler. Accordingly, we need to use an "ld4s" rather than "ld4u" to load and sign-extend for get_user(). This fixes glibc bug 14238 (see http://sourceware.org/bugzilla), introduced during the 3.5 merge window. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
2012-06-15swap: fix shmem swapping when more than 8 areasHugh Dickins2-11/+9
Minchan Kim reports that when a system has many swap areas, and tmpfs swaps out to the ninth or more, shmem_getpage_gfp()'s attempts to read back the page cannot locate it, and the read fails with -ENOMEM. Whoops. Yes, I blindly followed read_swap_header()'s pte_to_swp_entry( swp_entry_to_pte()) technique for determining maximum usable swap offset, without stopping to realize that that actually depends upon the pte swap encoding shifting swap offset to the higher bits and truncating it there. Whereas our radix_tree swap encoding leaves offset in the lower bits: it's swap "type" (that is, index of swap area) that was truncated. Fix it by reducing the SWP_TYPE_SHIFT() in swapops.h, and removing the broken radix_to_swp_entry(swp_to_radix_entry()) from read_swap_header(). This does not reduce the usable size of a swap area any further, it leaves it as claimed when making the original commit: no change from 3.0 on x86_64, nor on i386 without PAE; but 3.0's 512GB is reduced to 128GB per swapfile on i386 with PAE. It's not a change I would have risked five years ago, but with x86_64 supported for ten years, I believe it's appropriate now. Hmm, and what if some architecture implements its swap pte with offset encoded below type? That would equally break the maximum usable swap offset check. Happily, they all follow the same tradition of encoding offset above type, but I'll prepare a check on that for next.

These are all fixes, including one to prevent using stale pointers for device names, and lots of fixes around transaction abort cleanups (Josef, Liu Bo). Jan Schmidt also sent in a number of fixes for the new reference number tracking code. Liu Bo beat me to updating the MAINTAINERS file.

2012-06-15Btrfs: make sure that we've made everything in pinned tree cleanLiu Bo1-0/+11

2012-06-15Btrfs: avoid memory leak of extent state in error handling routineLiu Bo1-0/+2
We've forgotten to clear extent states in pinned tree, which will results in space counter mismatch and memory leak: WARNING: at fs/btrfs/extent-tree.c:7537 btrfs_free_block_groups+0x1f3/0x2e0 [btrfs]() ... space_info 2 has 8380416 free, is not full space_info total=12582912, used=4096, pinned=4096, reserved=0, may_use=0, readonly=4194304 btrfs state leak: start 29364224 end 29376511 state 1 in tree ffff880075f20090 refs 1 ...

2012-06-15Btrfs: fix missing inherited flag in renameLiu Bo1-3/+6
When we move a file into a directory with compression flag, we need to inherite BTRFS_INODE_COMPRESS and clear BTRFS_INODE_NOCOMPRESS as well. But if we move a file into a directory without compression flag, we need to clear both of them. It is the way how our setflags deals with compression flag, so keep the same behaviour here.
