register_memory() becomes double definition in 2.6.20-rc1. It is defined in arch/i386/kernel/setup.c as static definition in 2.6.19. But it is moved to arch/i386/kernel/e820.c in 2.6.20-rc1. And same name function is defined in driver/base/memory.c too. So, it becomes cause of compile error of duplicate definition if memory hotplug option is on. Signed-off-by:

Fix a bug that only appears when AoE goes over a network card that does not support scatter-gather. The headers in the linear part of the skb appeared to be larger than they really were, resulting in data that was offset by 24 bytes. This patch eliminates the offset data on cards that don't support scatter-gather or have had scatter-gather turned off. There remains an unrelated issue that I'll address in a separate email.

Trevor found a file size problem in eCryptfs in recent kernels, and he tracked it down to an fsstack change. This was the eCryptfs copy_attr_all: > -void ecryptfs_copy_attr_all(struct inode *dest, const struct inode *src) > -{ > - dest->i_mode = src->i_mode; > - dest->i_nlink = src->i_nlink; > - dest->i_uid = src->i_uid; > - dest->i_gid = src->i_gid; > - dest->i_rdev = src->i_rdev; > - dest->i_atime = src->i_atime; > - dest->i_mtime = src->i_mtime; > - dest->i_ctime = src->i_ctime; > - dest->i_blkbits = src->i_blkbits; > - dest->i_flags = src->i_flags; > -} This is the fsstack copy_attr_all: > +void fsstack_copy_attr_all(struct inode *dest, const struct inode *src, > + int (*get_nlinks)(struct inode *)) > +{ > + if (!get_nlinks) > + dest->i_nlink = src->i_nlink; > + else > + dest->i_nlink = (*get_nlinks)(dest); > + > + dest->i_mode = src->i_mode; > + dest->i_uid = src->i_uid; > + dest->i_gid = src->i_gid; > + dest->i_rdev = src->i_rdev; > + dest->i_atime = src->i_atime; > + dest->i_mtime = src->i_mtime; > + dest->i_ctime = src->i_ctime; > + dest->i_blkbits = src->i_blkbits; > + dest->i_flags = src->i_flags; > + > + fsstack_copy_inode_size(dest, src); > +} The addition of copy_inode_size breaks eCryptfs, since eCryptfs needs to interpolate the file sizes (eCryptfs has extra space in the lower file for the header). The setting of the upper inode size occurs elsewhere in eCryptfs, and the new copy_attr_all now undoes what eCryptfs was doing right beforehand. I see three ways of going forward from here. (1) Something like this patch needs to go in (assuming it jives with Unionfs), (2) we need to make a change to the fsstack API for more fine-grained control over copying attributes (e.g., by also including a callback function for calculating the right file size, which will require some more work on both eCryptfs and Unionfs), or (3) the fsstack patch on eCryptfs (commit 0cc72dc7 made on Fri Dec 8 02:36:31 2006 -0800) needs to be yanked in 2.6.20. I think the simplest solution, from eCryptfs' perspective, is to just remove the inode size copy. Remove inode size copy in general fsstack attr copy code. Stacked filesystems may need to interpolate the inode size, since the file size in the lower file may be different than the file size in the stacked layer.

Commit 2d7d2535 ("fix cond_resched() fix") introduced an 'expected_preempt_count' parameter to __resched_legal() to fix a bug where it was returning a false negative when called from cond_resched_lock() and preemption was enabled. Unfortunately this broke things for when preemption is disabled. preempt_count() will always return zero, thus failing the check against any value of expected_preempt_count not equal to zero. cond_resched_lock() for example, passes an expected_preempt_count value of 1. So fix the fix for the cond_resched() fix by skipping the check of preempt_count() against expected_preempt_count when preemption is disabled. Credit should go to Sunil Mushran for spotting the bug during testing. Signed-off-by:

The VM event counters, enabled by CONFIG_VM_EVENT_COUNTERS, which provides VM event counters in /proc/vmstat, has become more essential to non-EMBEDDED kernel configurations than they were in the past. Comments in the code and the Kconfig configuration explanation were stale, downplaying their role excessively. Refresh those comments to correctly reflect the current role of VM event counters.

truncate presently invalidates the dirty page's buffer_heads then shoots down the page. But try_to_free_buffers() will now bale out because the page is dirty. Net effect: the LRU gets filled with dirty pages which have invalidated buffer_heads attached. They have no ->mapping and hence cannot be cleaned. The machine leaks memory at an enormous rate. Fix this by cleaning the page before running try_to_free_buffers(), so try_to_free_buffers() can do its work. Also, remember to do dirty-page-acoounting in cancel_dirty_page() so the machine won't wedge up trying to write non-existent dirty pages. Probably still wrong, but now less so. Signed-off-by:
