From 5e1f8c9e20a92743eefc9a82c2db835213905e26 Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Tue, 28 Oct 2008 13:21:55 -0400 Subject: ext3: Add support for non-native signed/unsigned htree hash algorithms The original ext3 hash algorithms assumed that variables of type char were signed, as God and K&R intended. Unfortunately, this assumption is not true on some architectures. Userspace support for marking filesystems with non-native signed/unsigned chars was added two years ago, but the kernel-side support was never added (until now).

If somebody does a sync write or an fsync() traditionally we would sleep for 1 jiffies, which depending on the value of HZ could be a significant amount of time compared to how long it takes to commit a transaction to the underlying storage. With this patch instead of sleeping for a jiffie, we check to see if the amount of time this transaction has been running is less than the average commit time, and if it is we sleep for the delta using schedule_hrtimeout to give us a higher precision sleep time. This greatly benefits high end storage where you could end up sleeping for longer than it takes to commit the transaction and therefore sitting idle instead of allowing the transaction to be committed by keeping the sleep time to a minimum so you are sure to always be doing something.

This patch updates them to 64-bits but leaves the external API unchanged. Extending the external API is a separate issue for several reasons. First, no one needs it at the moment. Secondly, whether the implementation is done with IOCTLs, sysfs or both is still debated. Thirdly external API changes require the internal API to be accepted first. Note that although the MTD API will be able to support 64-bit device sizes, existing drivers do not and are not required to do so, although NAND base has been updated. In general, changing from 32-bit to 64-bit values cause little or no changes to the majority of the code with the following exceptions: - printk message formats - division and modulus of 64-bit values - NAND base support - 32-bit local variables used by mtdpart and mtdconcat - naughtily assuming one structure maps to another in MEMERASE ioctl Signed-off-by: Adrian Hunter Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse --- drivers/mtd/chips/cfi_cmdset_0001.c | 12 ++++---- drivers/mtd/chips/cfi_cmdset_0002.c | 8 +++--- drivers/mtd/chips/cfi_cmdset_0020.c | 14 ++++----- drivers/mtd/chips/fwh_lock.h | 4 +-- drivers/mtd/inftlcore.c | 2 +- drivers/mtd/inftlmount.c | 4 +-- drivers/mtd/maps/amd76xrom.c | 4 +-- drivers/mtd/maps/ck804xrom.c | 4 +-- drivers/mtd/maps/esb2rom.c | 4 +-- drivers/mtd/maps/ichxrom.c | 4 +-- drivers/mtd/maps/nettel.c | 2 +- drivers/mtd/maps/scb2_flash.c | 8 ++++-- drivers/mtd/mtdchar.c | 6 +++- drivers/mtd/mtdconcat.c | 33 ++++++++++++--------- drivers/mtd/mtdcore.c | 16 ++++++++++- drivers/mtd/mtdoops.c | 9 ++++-- drivers/mtd/mtdpart.c | 34 +++++++++++----------- drivers/mtd/nand/nand_base.c | 24 ++++++++++------ drivers/mtd/nand/nand_bbt.c | 31 ++++++++++---------- drivers/mtd/nftlcore.c | 2 +- drivers/mtd/nftlmount.c | 4 +-- drivers/mtd/onenand/onenand_base.c | 8 +++--- drivers/mtd/rfd_ftl.c | 23 ++++++++------- drivers/mtd/ssfdc.c | 7 +++-- drivers/mtd/ubi/build.c | 2 +- drivers/mtd/ubi/gluebi.c | 17 +++++------ fs/jffs2/erase.c | 5 ++-- include/linux/mtd/mtd.h | 57 +++++++++++++++++++++++++++++++------ include/linux/mtd/nand.h | 2 +- include/linux/mtd/partitions.h | 4 +-- 30 files changed, 216 insertions(+), 138 deletions(-) (limited to 'include') diff --git a/drivers/mtd/chips/cfi_cmdset_0001.c b/drivers/mtd/chips/cfi_cmdset_0001.c index c93a8be5d5f1..f5ab6fa1057b 100644 --- a/drivers/mtd/chips/cfi_cmdset_0001.c +++ b/drivers/mtd/chips/cfi_cmdset_0001.c @@ -58,8 +58,8 @@ static int cfi_intelext_write_buffers(struct mtd_info *, loff_t, size_t, size_t static int cfi_intelext_writev(struct mtd_info *, const struct kvec *, unsigned long, loff_t, size_t *);

After the system awakes from an S4 state, OSPM will restore this memory area and call the _WAK control method to enable the BIOS to reclaim its memory image."

Also eliminate the GetFirmwareWakingVector interface, as it served no purpose (only the firmware reads the vector, OS only writes the vector.)

The length must be divided by two in order to use these to access the status registers. 2) Add run-time option to use default register lengths to override a faulty FADT. 3) Add warning message if any of the X64 address structures contain a length that does not match the legacy length earlier in the FADT. 4) Move all FADT warning messages into the ValidateFadt function.
