2006-07-11[PATCH] nfs: Update Documentation/nfsroot.txt to include dhcp, syslinux and ↵Horms1-115/+160
isolinux * Document the ip command a little differently to make the interaction between defaults and autoconfiguration a little clearer (I hope) * Update autoconfiguration the current set of options, including DHCP * Update the boot methods to add syslinux and isolinux, and remove dd of=/dev/fd0 which is no longer supported by linux * Add a referance to initramfs along side initrd. Should the latter and its document be removed some time soon? * Various cleanups to put the text consistently into the thrid person * Reformated a bit to fit into 80 columns a bit more nicely * Should the bootloaders documentation be removed or split into a separate documentation, it seems somewhat out of scope Signed-off-by: Horms <horms@verge.net.au> Cc: "H.

2006-07-11[PATCH] reiserfs: fix journaling issue regarding fsync()Hisashi Hifumi1-1/+5
When write() extends a file(i_size is increased) and fsync() is called, change of inode must be written to journaling area through fsync(). But,currently the i_trans_id is not correctly updated when i_size is increased. So fsync() does not kick the journal writer. Reiserfs_file_write() already updates the transaction when blocks are allocated, but the case when i_size increases and new blocks are not added is not correctly treated. Following patch fix this bug.

2006-07-11[PATCH] SELinux: add rootcontext= option to label root inode when mountingEric Paris1-9/+57
Introduce a new rootcontext= option to FS mounting. This option will allow you to explicitly label the root inode of an FS being mounted before that FS or inode because visible to userspace.

2006-07-11[PATCH] SELinux: decouple fscontext/context mount optionsEric Paris2-16/+56
Remove the conflict between fscontext and context mount options. If context= is specified without fscontext it will operate just as before, if both are specified we will use mount point labeling and all inodes will get the label specified by context=. The superblock will be labeled with the label of fscontext=, thus affecting operations which check the superblock security context, such as associate permissions.

2006-07-11[PATCH] sched: fix bug in __migrate_task()Peter Williams1-1/+1
Problem: In the function __migrate_task(), deactivate_task() followed by activate_task() is used to move the task from one run queue to another. This has two undesirable effects: 1. The task's priority is recalculated. (Nowhere else in the scheduler code is the priority recalculated for a change of CPU.) 2. The task's time stamp is set to the current time. At the very least, this makes the adjustment of the time stamp before the call to deactivate_task() redundant but I believe the problem is more serious as the time stamp now holds the time of the queue change instead of the time at which the task was woken. In addition, unless dest_rq is the same queue as "current" is on the time stamp could be inaccurate due to inter CPU drift. Solution: Replace the call to activate_task() with one to __activate_task().

2006-07-11[PATCH] don't select CONFIG_HOTPLUGAndrew Morton3-4/+3
It's useful to be able to turn off CONFIG_HOTPLUG for compile-coverage testing and for section-checking coverage. But a few things go and select CONFIG_HOTPLUG, making it a royal PITA to turn the thing off. It's only turnable offable if CONFIG_EMBEDDED anyway. So let's make those things depend on HOTPLUG, not select it.

2006-07-06[PATCH] libata: reimplement controller-wide PMTejun Heo3-7/+298
Reimplement controller-wide PM. ata_host_set_suspend/resume() are defined to suspend and resume a host_set. While suspended, EHs for all ports in the host_set are pegged using ATA_FLAG_SUSPENDED and frozen. Because SCSI device hotplug is done asynchronously against the rest of libata EH and the same mutex is used when adding new device, suspend cannot wait for hotplug to complete. So, if SCSI device hotplug is in progress, suspend fails with -EBUSY. In most cases, host_set resume is followed by device resume. As each resume operation requires a reset, a single host_set-wide resume operation may result in multiple resets. To avoid this, resume waits upto 1 second giving PM to request resume for devices.

2006-07-06[PATCH] libata: reimplement per-dev PMTejun Heo3-92/+115
Reimplement per-dev PM. The original implementation directly put the device into suspended mode and didn't synchronize w/ EH operations including hotplug. This patch reimplements ata_scsi_device_suspend() and ata_scsi_device_resume() such that they request EH to perform the respective operations. Both functions synchronize with hotplug such that it doesn't operate on detached devices. Suspend waits for completion but resume just issues request and returns. This allows parallel wake up of devices and thus speeds up system resume. Due to sdev detach synchronization, it's not feasible to separate out EH requesting from sdev handling; thus, ata_device_suspend/resume() are removed and everything is implemented in the respective libata-scsi functions.
