From: Linus Torvalds <email@example.com> To: Kernel Mailing List <firstname.lastname@example.org> Subject: linux-2.5.4-pre1 - bitkeeper testing Date: Tue, 5 Feb 2002 19:37:41 -0800 (PST) Ok, I've spent about a week trying to change my working habits and scripting bitkeeper enough to (a) import a good revision controlled tree into it from the 2.4.x and 2.5.x patch-archives and (b) try to actually accept patches directly into bitkeeper. Quite frankly, so far it has definitely made me slower - it took me basically a week to get about 50 patches applied, but most of that time by far was writing scripts and just getting used to the thing. Thanks to Larry and Wayne for helping out with the problems I had. And I'm not even done yet. I expect to be a bit slower to react to patches for a while yet, until the scripts are better. However, some of it pays off already. Basically, I'm aiming to be able to accept patches directly from email, with the comments in the email going into the revision control history. For a first example, the ChangeLog file for 2.5.4-pre1 is rather more detailed than usual (in fact, right now it is _too_ detailed, and I haven't written the scripts to "terse it down" for postings to linux-kernel, for example). The long-range plan, and the real payoff, comes if main developers start using bk too, which should make syncing a lot easier. That will take some time, I suspect.

This chip is used in various PCI ISDN adapters (it's an PCI interface chip) and has an erratum when the BAR 0/1 has bit 7 set (the size of the region is 0x80, so aligning it to 0x80 is legal and really happens for people). This workaround has been tested by a user who hit this problem with a Gazel card. Basically the same fix has been done for Elsa cards, but it's untested.

ChangeSet@1.209, 2002-02-05 17:24:21-08:00, firstname.lastname@example.org [PATCH] Drop reliance on file->f_dentry in NFS reads/writes Following a request by David Chow on linux fsdevel, this patch causes NFS read and write requests to take the inode from page->mapping->host rather than relying on file->f_dentry->d_inode. Apparently this will simplify some work he is doing on another filesystem. In any case, it cleans up the current mix of sometimes doing one thing, sometimes the other (historical cruft), and puts NFS client behaviour on par with what is done in other filesystems... ChangeSet@1.208, 2002-02-05 17:24:18-08:00, email@example.com [PATCH] Fix spurious ETXTBSY errors due to late release of struct file The following patch should fix a problem of ETXTBSY sometimes occurring if one tries to run a file straight after compilation. The problem is that both NFS read and write requests can currently hold a count on the struct file. This is done partly so as to be able to pass along the RPC credential (which is cached in the struct file), and partly so that asynchronous writes can report any errors via the file->f_error mechanism. The problem is that both the read and write requests may persist even after file close() occurs. For O_RDONLY files, this is not a problem, but for O_WRONLY, and O_RDWR files, the fact that the struct file is not released until the last call to nfs_release_request() means that inode->i_writecount does not necessarily get cleared upon file close(). The following patch fixes both these issues. - NFS read requests no longer hold the struct file. They take a count on the the RPC credential itself. - NFS write requests still hold the struct file, since they want to report errors to sys_close() using the file->f_error mechanism. However they are made to release the page, credential, and file structures as soon as the write is completed instead of following the current practice of waiting for the last nfs_page request release.

VFS fix removed. (I'll resend the 'uses d_revalidate()' version separately after a suitable delay to allow for comments.) Issues fixed by this patch: - Use the directory mtime in order to give us a hint when we should check for namespace changes. - Add support for the 'nocto' flag, in order to turn off the strict attribute cache revalidation on file open(). - Simplify inode lookup. Don't check the 'fsid' field (which appears to be buggy in too many servers in order to be reliable). Instead we only rely on the inode number (a.k.a. 'fileid') and the (supposedly unique) filehandle.

Besides problem with segfaulting crc32 (it is initialized after net/ipv4/ipconfig.c due to lib/lib.a being a library... I had to hardcode lib/crc32.o before --start-group in main Makefile, but it is another story) there is bad problem with NBD caused by BIO changes: (1) request flags were immediately put into on-wire request format. In the past, we had 0=READ, !0=WRITE. Now only REQ_RW bit determines direction. As nbd-server from nbd distribution package treats any non-zero value as write, it performs writes instead of read. Fortunately it will die due to other consistency checks on incoming request, but... (2) nbd servers handle only up to 10240 byte requests. So setting max_sectors to 20 is needed, as otherwise nbd server commits suicide. Maximum request size should be handshaked during nbd initialization, but currently just use hardwired 20 sectors, so it will behave like it did in the past.
