[PATCH 1/1] fix-taskstates-in-sched_switch-trace.patch
The sched_switch trace event displays erroneous character codes of task states, after a new task state was added in the scheduler code but omitted to add in the trace event code. Define character codes of task states individually. In addition, define task state descriptions needed in /proc at the same place. This... 11 Mar 2010 08:54

[PATCH 0/1] tracing: Fix erroneous task states in sched_switch event
A recent change in the task state definitions was omitted to apply to the sched_switch event output. In addition, move task state definitions to a common place. This ensures that future changes make it to all places where needed. Carsten. -- To unsubscribe from this list: send the line "unsubscribe... 11 Mar 2010 08:54

[PATCH v8 7/7] TCPCT part 2g: parse cookie pair and 64-bit timestamp
Every bit is sacred. Use as few bits as possible in tcp_options_received. Group related timestamp flag bits for cache line memory efficiency. Fix #define spacing for TCP options. Define and parse 64-bit timestamp extended option (and minor cleanup). However, only 32-bits are used at this time (permitted by spe... 11 Mar 2010 08:54

RAID + LUKS + LVM performance
Hi, (please cc me as I'm not subscribed) I've a friend who's going to set up a fileserver consisting of 8x 1.5TB HDDs, an 8-port PCI-E RAID card (Areca ARC-1220 @ http://www.areca.com.tw/products/pcie.htm ) etc. The plan is create a RAID5 array spanning all the disks, then create 4 partitions. These 4 parti... 12 Mar 2010 11:39

[PATCH] perf: Make the install relative to DESTDIR if specified
Without this change, the install path is relative to prefix/DESTDIR where prefix is automatically set to $HOME This can produce unexpected results. For example make -C tools/perf DESTDIR=/home/jkacur/tmp install-man creates the directory: /home/jkacur/home/jkacur/tmp/share/... instead of the expected: /ho... 11 Mar 2010 08:54

[PATCH v6 6/7] TCPCT part 2f: cleanup tcp_parse_options
Split switch, shift cases to the left, fix most lines beyond column 80. Add error return. Harmonize parameter order with other tcp_input functions: tcp_fast_parse_options() and tcp_validate_incoming(). Harmonize initialization in syncookies. Fix initialization in tcp_minisocks. Repair net/ipv4/tcp_ipv4.c ... 11 Mar 2010 08:54

[PATCH v3 5/7] TCPCT part 2e: accept SYNACK data
When accompanied by cookie option, Initiator (client) queues incoming SYNACK transaction data. This is a straightforward re-implementation of an earlier (18 month old) patch that no longer applies cleanly, with permission of the original author (Adam Langley). The patch was previously reviewed: http://thr... 11 Mar 2010 07:48

[PATCH v6 4/7] tcp: input header length, prediction, and timestamp bugs
Fix incorrect header prediction flags documentation. Relieve register pressure in (the i386) fast path by accessing skb->len directly, instead of carrying a rarely used len parameter. Eliminate unused len parameters in two other functions. Don't use output calculated tp->tcp_header_len for input decisions. W... 11 Mar 2010 07:48

[PATCH v6 3/7] tcp: harmonize tcp_vx_rcv header length assumptions
Harmonize tcp_v4_rcv() and tcp_v6_rcv() -- better document tcp doff and header length assumptions, and carefully compare implementations. Reduces multiply/shifts, marginally improving speed. Removes redundant tcp header length checks before checksumming. Instead, assumes (and documents) that any backlog proce... 11 Mar 2010 07:48
