* fs: Add new pre-allocation ioctls to vfs for compatibility with legacy xfs ↵Ankit Jain2009-06-24
| | | | | | | | | | | | | | | | ioctls This patch adds ioctls to vfs for compatibility with legacy XFS pre-allocation ioctls (XFS_IOC_*RESVP*). The implementation effectively invokes sys_fallocate for the new ioctls. Also handles the compat_ioctl case. Note: These legacy ioctls are also implemented by OCFS2.

* cleanup __writeback_single_inodeChristoph Hellwig2009-06-24
| | | | | | | | | | | | There is no reason to for the split between __writeback_single_inode and __sync_single_inode, the former just does a couple of checks before tail-calling the latter. So merge the two, and while we're at it split out the I_SYNC waiting case for data integrity writers, as it's logically separate function. Finally rename __writeback_single_inode to writeback_single_inode. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

* Make allocation of anon devices cheaperAl Viro2009-06-24
| | | | | | | | | | | | | | | | | | | Standard trick - add a new variable (start) such that for each n < start n is known to be busy. Allocation can skip checking everything in [0..start) and if it returns n, we can set start to n + 1. Freeing below start sets start to what we'd just freed. Of course, it still sucks if we do something like free 0 allocate allocate in a loop - still O(n^2) time. However, on saner loads it improves the things a lot and the entire thing is not worth the trouble of switching to something with better worst-case behaviour.

* mm: fix handling of pagesets for downed cpusDimitri Sivanich2009-06-23
| | | | | | | | | | | | | | | | | | | | | | After downing/upping a cpu, an attempt to set /proc/sys/vm/percpu_pagelist_fraction results in an oops in percpu_pagelist_fraction_sysctl_handler(). If a processor is downed then we need to set the pageset pointer back to the boot pageset. Updates of the high water marks should not access pagesets of unpopulated zones (those pointer go to the boot pagesets which would be no longer functional if their size would be increased beyond zero).

| | | | | | | | | | | | | | | | | | | | | | | | | | | After the recent changes that went into mm/vmscan.c to overhaul stuff, we ended up with these warnings on no-mmu systems: mm/vmscan.c: In function `shrink_page_list': mm/vmscan.c:580: warning: unused variable `vm_flags' mm/vmscan.c: In function `shrink_active_list': mm/vmscan.c:1294: warning: `vm_flags' may be used uninitialized in this function mm/vmscan.c:1242: note: `vm_flags' was declared here This is because the no-mmu function defines page_referenced() to work on the first argument only (the page). It does not clear the vm_flags given to it because for no-mmu systems, they never actually get utilized. Since that is no longer strictly true, we need to set vm_flags to 0 like everyone else so gcc can do proper dead code elimination without annoying us with unused warnings.

* mm: pass mm to grab_swap_tokenHugh Dickins2009-06-23
| | | | | | | | | | | | | | | | | | | | If a kthread happens to use get_user_pages() on an mm (as KSM does), there's a chance that it will end up trying to read in a swap page, then oops in grab_swap_token() because the kthread has no mm: GUP passes down the right mm, so grab_swap_token() ought to be using it. We have not identified a stronger case than KSM's daemon (not yet in mainline), but the issue must have come up before, since RHEL has included a fix for this for years (though a different fix, they just back out of grab_swap_token if current->mm is unset: which is what we first proposed, but using the right mm here seems more correct).

While the ehca driver is loaded, dynamic memory operations are still prohibited by returning NOTIFY_BAD from the memory notifier. On module load the driver walks through available system memory, checks for available memory ranges and then registers the kernel internal memory region accordingly.

It accepts an integer bitmask for logging. Currently it supports: bit LSB 0 = general libfc debugging 1 = lport debugging 2 = disc debugging 3 = rport debugging 4 = fcp debugging 5 = EM debugging 6 = exch/seq debugging 7 = scsi logging (mostly error handling) the other bits are not used at this time. The patch converts all of the libfc source files to use these new macros and removes the old FC_DBG macro.

| * | | libfcoe: Add runtime debugging with module param debug_loggingRobert Love2009-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a 'debug_logging' module parameter to libfcoe.ko. It is an unsigned int that represents a bitmask of available debug logging levels, each of which can be tuned at runtime. Currently there are only two logging levels for this module- bit LSB 0 = libfcoe general logging 1 = FIP logging Signed-off-by: Robert Love <robert.w.love@intel.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
