2005-07-27JFS: Improve sync barrier processingDave Kleikamp
Under heavy load, hot metadata pages are often locked by non-committed transactions, making them difficult to flush to disk. This prevents the sync point from advancing past a transaction that had modified the page. There is a point during the sync barrier processing where all outstanding transactions have been committed to disk, but no new transaction have been allowed to proceed. This is the best time to write the metadata. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>

2005-07-26JFS: Fix i_blocks accounting when allocation failsDave Kleikamp
A failure in dbAlloc caused a directory's i_blocks to be incorrectly incremented, causing jfs_fsck to find the inode to be corrupt. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>
2005-07-25JFS: Don't set log_SYNCBARRIER when log->active == 0Dave Kleikamp
If a metadata page is kept active, it is possible that the sync barrier logic continues to trigger, even if all active transactions have been phyically written to the journal. This can cause a hang, since the completion of the journal I/O is what unsets the sync barrier flag to allow new transactions to be created. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>

2005-07-22Remove "noreplacement" kernel command line option.Linus Torvalds
It is no longer valid to not replace instructions, since we depend on different behaviour depending on CPU capabilities. If you need to limit the capabilities of the replacements (because the boot CPU has features that non-boot CPU's do not have, for example), you need to explicitly disable those capabilities that are not shared across all CPU's. For example, if your boot CPU has FXSR, but other CPU's in your system do not, you need to use the "nofxsr" kernel command line, not disable instruction replacement per se.
2005-07-22x86: use alternative instructions for fnsave/fxsave tooLinus Torvalds
This one ends up using an inline asm format that claims to read memory and then clobber it (rather than just write it directly), which made it easier to use the existing "alternative_input()" infrastructure support. Now the fxsave code matches the fxrstor.

2005-07-22x86: make restore_fpu() use alternative assembler instructionsLinus Torvalds
It's really just a single instruction, conditional on whether the CPU supports FXSR or not, so implement it as such instead of making it a function that queries FXSR dynamically. This means that the instruction just gets automatically rewritten to the correct one at boot-time.

2005-07-22Fix up incorrect "unlikely()" on %gs reload in x86 __switch_toLinus Torvalds
These days %gs is normally the TLS segment, so it's no longer zero. As a result, we shouldn't just assume that %fs/%gs tend to be zero together, but test them independently instead. Also, fix setting of debug registers to use the "next" pointer instead of "current". It so happens that the scheduler will have set the new current pointer before calling __switch_to(), but that's just an implementation detail.

2005-07-21[NETFILTER]: ip_conntrack_expect_related must not free expectationRusty Russell
If a connection tracking helper tells us to expect a connection, and we're already expecting that connection, we simply free the one they gave us and return success. The problem is that NAT helpers (eg. FTP) have to allocate the expectation first (to see what port is available) then rewrite the packet. If that rewrite fails, they try to remove the expectation, but it was freed in ip_conntrack_expect_related. This is one example of a larger problem: having registered the expectation, the pointer is no longer ours to use. Reference counting is needed for ctnetlink anyway, so introduce it now. To have a single "put" path, we need to grab the reference to the connection on creation, rather than open-coding it in the caller.
