From cbc3d65ebcb0c494183d45cf202a53352cbf3871 Mon Sep 17 00:00:00 2001 From: Dave Kleikamp Date: Wed, 27 Jul 2005 09:17:57 -0500 Subject: [PATCH 001/116] JFS: Improve sync barrier processing 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.

First of all, this can only occur if cnt > 1 since tp->packets_out is never zero here. If it did hit zero we'd have much bigger problems. So cnt is equal to fackets_out - reordering. Normally fackets_out is less than packets_out. The only reason I've found that might cause fackets_out to exceed packets_out is if tcp_fragment is called from tcp_retransmit_skb with a TSO skb and the current MSS is greater than the MSS stored in the TSO skb. This might occur as the result of an expiring dst entry. In that case, packets_out may decrease (line 1380-1381 in tcp_output.c). However, fackets_out is unchanged which means that it may in fact exceed packets_out. Previously tcp_retrans_try_collapse was the only place where packets_out can go down and it takes care of this by decrementing fackets_out. So we should make sure that fackets_out is reduced by an appropriate amount here as well. Signed-off-by: Herbert Xu Signed-off-by: David S.

Daplas" Date: Mon, 15 Aug 2005 21:29:11 +0800 Subject: [PATCH 031/116] [PATCH] intelfb/fbdev: Save info->flags in a local variable Reported by: Pavel Kysilka (Bugzilla Bug 5059) The intelfb driver does not keep resolution set with fbset after switching to anot console and back. Steps to reproduce: initial options: tty1,tty2 - 1024x768-60 1) tty1 - fbset after booting (1024x768-60) 2) tty1 - fbset 800x600-100 tty1: 800x600-100 3) swith to tty2, swith to tty1 tty1: 1024x768-60 (the same resolution as default from kernel booting) This bug is caused by intelfb unintentionally destroying info->flags in set_par(). Therefore the flag, FBINFO_MISC_USEREVENT used to notify fbcon of a mode change was cleared causing the above problem. This bug though is not intelfb specific, as other drivers may also be affected. The fix is to save info->flags in a local variable before calling any of the driver hooks. A more definitive fix (for post 2.6.13) is to separate info->flags into one that is set by the driver and another that is set by core fbdev/fbcon.

It does this since an NFSv3/v4 exclusive create cannot immediately set the mode bits. The 01777 mode then gets put into the inode->i_mode. After the file creation is successful, we then do a setattr to change the mode to the correct value (as per the NFS spec). The problem is that nfs_refresh_inode() no longer updates inode->i_mode, so the latter retains the 01777 mode. A bit later, the VFS notices this, and calls remove_suid(). This of course now resets the file mode to inode->i_mode & 0777. Hey presto, the file mode on the server is now magically changed to 0777. Duh...

The first fragment is then sent out. At this point the remaining fragment is allocated by tcp_fragment. However, its size is padded to fit the L1 cache-line size therefore creating tail-room up to 124 bytes long. This fragment will also be sitting at sk_send_head. 4) tcp_sendmsg is called again and it stores data in the tail-room of of the fragment. 5) tcp_push_one is called by tcp_sendmsg which then calls tso_fragment since the packet as a whole exceeds the MTU. At this point we have a packet that has data in the head area being fed to tso_fragment which bombs out. My take on this is that we shouldn't ever call tcp_fragment on a TSO socket for a packet that is yet to be transmitted since this creates a packet on sk_send_head that cannot be extended. So here is a patch to change it so that tso_fragment is always used in this case. Signed-off-by: Herbert Xu Signed-off-by: David S.

This doesn't get around the problem of having it at a fixed address, but it makes it more palatable. It would be good if this could be included in 2.6.13 as it solves our build problems with various versions of binutils and gcc. In particular, it allows us to build an iSeries kernel on Debian unstable using their biarch compiler. This has been built and booted on iSeries and built for pSeries and g5.

I'm not sure if duplicate mappings do any harm, but it's simply redundant. Also, in s3c2440.c the UART I/O mapping is NOT done. Additionally, I put a comma behind the last mapping, to ease copy/pasting stuff around, and make the style consistent with s3c2440.c and other files.

The first fragment is then sent out. At this point the remaining fragment is allocated by tcp_fragment. However, its size is padded to fit the L1 cache-line size therefore creating tail-room up to 124 bytes long. This fragment will also be sitting at sk_send_head. 4) tcp_sendmsg is called again and it stores data in the tail-room of of the fragment. 5) tcp_push_one is called by tcp_sendmsg which then calls tso_fragment since the packet as a whole exceeds the MTU. At this point we have a packet that has data in the head area being fed to tso_fragment which bombs out. My take on this is that we shouldn't ever call tcp_fragment on a TSO socket for a packet that is yet to be transmitted since this creates a packet on sk_send_head that cannot be extended. So here is a patch to change it so that tso_fragment is always used in this case. Signed-off-by: Herbert Xu Signed-off-by: David S.

Using bitops means we can use a generic wait_on_bit call instead of an ad hoc locking scheme in fs/nfs/inode.c, so we can remove the "nfs_i_wait" field from nfs_inode at the same time. The other new flags field will continue to use bitmask and logic AND and OR. This permits several flags to be set at the same time efficiently. The following patch adds a spin lock to protect these flags, and this spin lock will later cover other fields in the nfs_inode structure, amortizing the cost of using this type of serialization. Test plan: Millions of fsx ops on SMP clients.

Note this change addresses an SMP hang found by njw@osdl.org, where processes deadlock because nfs_end_data_update and nfs_revalidate_mapping update the "cache_validity" field without proper serialization. Test plan: Millions of fsx ops on SMP clients. Run Nick Wilson's breaknfs program on large SMP clients.

As the array can be created with a different md device, it is mostly an inconvenience. I'm pretty sure there is no risk of data corruption.
