Fix various silly problems wrt mnt_namespace.h: - exit_mnt_ns() isn't used, remove it - done that, sched.h and nsproxy.h inclusions aren't needed - mount.h inclusion was need for vfsmount_lock, but no longer - remove mnt_namespace.h inclusion from files which don't use anything from mnt_namespace.h Signed-off-by:

In testing a backport of the write_begin/write_end AOPs, a 10% re-read regression was noticed when running iozone. This regression was introduced because the old AOPs would always do a mark_page_accessed(page) after the commit_write, but when the new AOPs where introduced, the only place this was kept was in pagecache_write_end(). This patch does the same thing in the generic case as what is done in pagecache_write_end(), which is just to mark the page accessed before we do write_end(). Signed-off-by:

Fix the multithread program core thread message error. This issue affects arches with neither has CORE_DUMP_USE_REGSET nor ELF_CORE_COPY_TASK_REGS, ARM is one of them. The thread message of core file is generated in elf_dump_thread_status. The register values is set by elf_core_copy_task_regs in this function. If an arch doesn't define ELF_CORE_COPY_TASK_REGS, elf_core_copy_task_regs() will do nothing. Then the core file will not have the register message of thread. So add elf_core_copy_regs to set regiser values if ELF_CORE_COPY_TASK_REGS doesn't define. The following is how to reproduce this issue: cat 1.c #include <stdio.h> #include <pthread.h> #include <assert.h> void td1(void * i) { while (1) { printf ("1\n"); sleep (1); } return; } void td2(void * i) { while (1) { printf ("2\n"); sleep (1); } return; } int main(int argc,char *argv[],char *envp[]) { pthread_t t1,t2; pthread_create(&t1, NULL, (void*)td1, NULL); pthread_create(&t2, NULL, (void*)td2, NULL); sleep (10); assert(0); return (0); } arm-xxx-gcc -g -lpthread 1.c -o 1 copy 1.c and 1 to a arm board. Goto this board. ulimit -c 1800000 ./1 # ./1 1 2 1 ... ... 1 1: 1.c:37: main: Assertion `0' failed. Aborted (core dumped) Then you can get a core file. gdb 1 core.xxx Without the patch: (gdb) info threads 3 process 909 0x00000000 in ?? () 2 process 908 0x00000000 in ??

I run many ffsb test cases on JBODs (typically 13/12 disks). Comparing with kernel 2.6.30, 2.6.31-rc1 has about 16% regression with ffsb_create_4k. The sub test case creates files continuously for 10 minitues and every file is 1MB. Bisect located below patch. 5cee5815 is first bad commit commit 5cee5815 Author: Jan Kara <jack@suse.cz> Date: Mon Apr 27 16:43:51 2009 +0200 vfs: Make sys_sync() use fsync_super() (version 4) It is unnecessarily fragile to have two places (fsync_super() and do_sync()) doing data integrity sync of the filesystem. Alter __fsync_super() to accommodate needs of both callers and use it. So after this patch __fsync_super() is the only place where we gather all the calls needed to properly send all data on a filesystem to disk. As a matter of fact, ffsb calls sys_sync in the end to make sure all data is flushed to disks and the flushing is counted into the result. vmstat shows ffsb is blocked when syncing for a long time. With 2.6.30, ffsb is blocked for a short time. I checked the patch and did experiments to recover the original methods. Eventually, the root cause is the patch deletes the calling to wakeup_pdflush when syncing, so only ffsb is blocked on disk I/O. wakeup_pdflush could ask pdflush to write back pages with ffsb at the same time.

Commit 'net: Move rx skb_orphan call to where needed' broken sctp protocol with warning at inet_sock_destruct(). Actually, sctp can do this right with sctp_sock_rfree_frag() and sctp_skb_set_owner_r_frag() pair. sctp_sock_rfree_frag(skb); sctp_skb_set_owner_r_frag(skb, newsk); This patch not revert the commit d55d87fd, instead remove the sctp_sock_rfree_frag() function. ------------[ cut here ]------------ WARNING: at net/ipv4/af_inet.c:151 inet_sock_destruct+0xe0/0x142() Modules linked in: sctp ipv6 dm_mirror dm_region_hash dm_log dm_multipath scsi_mod ext3 jbd uhci_hcd ohci_hcd ehci_hcd [last unloaded: scsi_wait_scan] Pid: 1808, comm: sctp_test Not tainted 2.6.31-rc2 #40 Call Trace: [<c042dd06>] warn_slowpath_common+0x6a/0x81 [<c064a39a>] ? inet_sock_destruct+0xe0/0x142 [<c042dd2f>] warn_slowpath_null+0x12/0x15 [<c064a39a>] inet_sock_destruct+0xe0/0x142 [<c05fde44>] __sk_free+0x19/0xcc [<c05fdf50>] sk_free+0x18/0x1a [<ca0d14ad>] sctp_close+0x192/0x1a1 [sctp] [<c0649f7f>] inet_release+0x47/0x4d [<c05fba4d>] sock_release+0x19/0x5e [<c05fbab3>] sock_close+0x21/0x25 [<c049c31b>] __fput+0xde/0x189 [<c049c3de>] fput+0x18/0x1a [<c049988f>] filp_close+0x56/0x60 [<c042f422>] put_files_struct+0x5d/0xa1 [<c042f49f>] exit_files+0x39/0x3d [<c043086a>] do_exit+0x1a5/0x5dd [<c04a86c2>] ? d_kill+0x35/0x3b [<c0438fa4>] ? dequeue_signal+0xa6/0x115 [<c0430d05>] do_group_exit+0x63/0x8a [<c0439504>] get_signal_to_deliver+0x2e1/0x2f9 [<c0401d9e>] do_notify_resume+0x7c/0x6b5 [<c043f601>] ? autoremove_wake_function+0x0/0x34 [<c04a864e>] ? __d_free+0x3d/0x40 [<c04a867b>] ? d_free+0x2a/0x3c [<c049ba7e>] ? vfs_write+0x103/0x117 [<c05fc8fa>] ? sys_socketcall+0x178/0x182 [<c0402a56>] work_notifysig+0x13/0x19 ---[ end trace 9db92c463e789fba ]--- Signed-off-by:Wei Yongjun <yjwei@cn.fujitsu.com> Acked-by:
