2009-06-24pci: use pci_ioremap_bar() in drivers/serialArjan van de Ven2-6/+3
Use the newly introduced pci_ioremap_bar() function in drivers/serial. pci_ioremap_bar() just takes a pci device and a bar number, with the goal of making it really hard to get wrong, while also having a central place to stick sanity checks.

2009-06-24synclink_gt: fix transmit race and timeoutPaul Fulghum1-42/+30
Fix race condition when adding transmit data to active DMA buffer ring that can cause transmit stall. Update transmit timeout when adding data to active DMA buffer ring. Base transmit timeout on amount of buffered data instead of using fixed value.

Implement the serial polling hooks for the serial_txx9 uart for use with kgdboc. This patch once got SOB from Jason on Jul 2008 and (perhaps) merged into kgdb-next branch, but lost somewhere then.

2009-06-24reiserfs: minimal fix for ACL cachingAl Viro1-1/+1
reiserfs uses NULL as "unknown" and ERR_PTR(-ENODATA) as "no ACL"; several codepaths store the former instead of the latter. All those codepaths go through iset_acl() and all cases when it's called with NULL acl are for the second variety, so the minimal fix is to teach iset_acl() to deal with that. Proper fix is to switch to more usual conventions and avoid back and forth between internally used ERR_PTR(-ENODATA) and NULL expected by the rest of the kernel.

2009-06-24fs: Add new pre-allocation ioctls to vfs for compatibility with legacy xfs ↵Ankit Jain5-29/+139
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.

2009-06-24cleanup __writeback_single_inodeChristoph Hellwig1-50/+50
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>

2009-06-24Make allocation of anon devices cheaperAl Viro1-1/+6
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.

2009-06-24Audit: clean up all op= output to include string quotingEric Paris6-24/+24

2009-06-24Audit: move audit_get_nd completely into audit_watchEric Paris3-24/+23

2009-06-24Audit: dereferencing krule as if it were an audit_watchEric Paris1-34/+24
audit_update_watch() runs all of the rules for a given watch and duplicates them, attaches a new watch to them, and then when it finishes that process and has called free on all of the old rules (ok maybe still inside the rcu grace period) it proceeds to use the last element from list_for_each_entry_safe() as if it were a krule rather than being the audit_watch which was anchoring the list to output a message about audit rules changing. This patch unfies the audit message from two different places into a helper function and calls it from the correct location in audit_update_rules(). We will now get an audit message about the config changing for each rule (with each rules filterkey) rather than the previous garbage. Signed-off-by: Eric Paris <eparis@redhat.com>
2009-06-24Audit: better estimation of execve record lengthEric Paris1-2/+2
The audit execve record splitting code estimates the length of the message generated. But it forgot to include the "" that wrap each string in its estimation.
