2005-10-28[PATCH] usb: Patch for USBDEVFS_IOCTL from 32-bit programsPete Zaitcev1-0/+1
Dell supplied me with the following test: #include<stdio.h> #include<errno.h> #include<sys/ioctl.h> #include<fcntl.h> #include<linux/usbdevice_fs.h> main(int argc,char*argv[]) { struct usbdevfs_hub_portinfo hubPortInfo = {0}; struct usbdevfs_ioctl command = {0}; command.ifno = 0; command.ioctl_code = USBDEVFS_HUB_PORTINFO; command.data = (void*)&hubPortInfo; int fd, ret; if(argc != 2) { fprintf(stderr,"Usage: %s /proc/bus/usb/<BusNo>/<HubID>\n",argv[0]); fprintf(stderr,"Example: %s /proc/bus/usb/001/001\n",argv[0]); exit(1); } errno = 0; fd = open(argv[1],O_RDWR); if(fd < 0) { perror("open failed:"); exit(errno); } errno = 0; ret = ioctl(fd,USBDEVFS_IOCTL,&command); printf("IOCTL return status:%d\n",ret); if(ret<0) { perror("IOCTL failed:"); close(fd); exit(3); } else { printf("IOCTL passed:Num of ports %d\n",hubPortInfo.nports); close(fd); exit(0); } return 0; } I have verified that it breaks if built in 32 bit mode on x86_64 and that the patch below fixes it.

2005-10-28[PATCH] gfp_t: fs/*Al Viro19-45/+45
- ->releasepage() annotated (s/int/gfp_t), instances updated - missing gfp_t in fs/* added - fixed misannotation from the original sweep caught by bitwise checks: XFS used __nocast both for gfp_t and for flags used by XFS allocator. The latter left with unsigned int __nocast; we might want to add a different type for those but for now let's leave them alone. That, BTW, is a case when __nocast use had been actively confusing - it had been used in the same code for two different and similar types, with no way to catch misuses. Switch of gfp_t to bitwise had caught that immediately... One tricky bit is left alone to be dealt with later - mapping->flags is a mix of gfp_t and error indications. Left alone for now.

2005-10-28[patch] remove gendisk->stamp_idle fieldChen, Kenneth W1-1/+1
struct gendisk has these two fields: stamp, stamp_idle. Update to stamp_idle is always in sync with stamp and they are always the same. Therefore, it does not add any value in having two fields tracking same timestamp. Suggest to remove it. Also, we should only update gendisk stats with non-zero value. Advantage is that we don't have to needlessly calculate memory address, and then add zero to the content. Signed-off-by: Ken Chen <kenneth.w.chen@intel.com> Signed-off-by: Jens Axboe <axboe@suse.de>

2005-10-27NFS: nfs_lookup doesn't need to revalidate the parent directory's inodeChuck Lever1-6/+0
nfs_lookup() used to consult a lookup cache before trying an actual wire lookup operation. The lookup cache would be invalid, of course, if the parent directory's mtime had changed, so nfs_lookup performed an inode revalidation on the parent. Since nfs_lookup() doesn't use a cache anymore, the revalidation is no longer necessary. There are cases where it will generate a lot of unnecessary GETATTR traffic. See http://bugzilla.linux-nfs.org/show_bug.cgi?id=9 Test-plan: Use lndir and "rm -rf" and watch for excess GETATTR traffic or application level errors.

2005-10-27NFS: Don't let nfs_end_data_update() clobber attribute update informationTrond Myklebust4-24/+63
Since we almost always call nfs_end_data_update() after we called nfs_refresh_inode(), we now end up marking the inode metadata as needing revalidation immediately after having updated it. This patch rearranges things so that we mark the inode as needing revalidation _before_ we call nfs_refresh_inode() on those operations that need it.

2005-10-27NFS: Optimise inode attribute cache updatesTrond Myklebust4-19/+41

2005-10-26[PATCH] Fix HFS+ to free up the space when a file is deleted.Peter Wainwright1-0/+1
fsck_hfs reveals lots of temporary files accumulating in the hidden directory "\000\000\000HFS+ Private Data". According to the HFS+ documentation these are files which are unlinked while in use. However, there may be a bug in the Linux hfsplus implementation which causes this to happen even when the files are not in use. It looks like the "opencnt" field is never initialized as (I think) it should be in hfsplus_read_inode. This means that a file can appear to be still in use when in fact it has been closed. This patch seems to fix it for me.

2005-10-23[PATCH] inotify/idr leak fixAndrew Morton1-0/+1
Fix a bug which was reported and diagnosed by Stefan Jones <stefan.jones@churchillrandoms.co.uk> IDR trees include a cache of idr_layer objects. There's no way to destroy this cache, so when we discard an overall idr tree we end up leaking some memory. Add and use idr_destroy() for this. v9fs and infiniband also need to use idr_destroy() to avoid leaks. Or, we make the cache global, like radix_tree_preload(). Which is probably better. Later.
