There is a double free in the scsi scan code if a LLDD's slave_alloc() call fails. There is a direct call to scsi_free_queue and then the following put_device calls the release function, which also frees the queue. Remove the redundant scsi_free_queue.

This reverts commit 1b0997f5, which in turn reverted 34ea80ec (which is thus re-instated). Quoth James Bottomley: "All it's doing is deferring the device_put() from the scsi_put_command() to after the scsi_run_queue(), which doesn't fix the sleep while atomic problem of the device release method. In both cases we still get the semaphore in atomic context problem which is caused by scsi_reap_target() doing a device_del(), which I assumed (wrongly) was valid from atomic context." who also promised to fix scsi_reap_target().

The raid5 stripe cache was recently changed from fixed size (NR_STRIPES) to variable size (conf->max_nr_stripes). However there are two places that still use the constant and as a result, reducing the size of the stripe cache can result in a deadlock.

This has been broken for months. On resume, we call acpi_pci_link_set() with interrupts off, so we get a warning when we try to do a kmalloc of non atomic memory. The actual allocation is just 2 long's (plus extra byte for some reason I can't fathom), so a simple conversion to GFP_ATOMIC is probably the safest way to fix this. The error looks like this..

Hitting BUG_ON() in __alloc_bootmem_core() when there is no free page available in the first node's memory. For the case of kdump on PPC64 (Power 4 machine), the captured kernel is used two memory regions - memory for TCE tables (tce-base and tce-size at top of RAM and reserved) and captured kernel memory region (crashk_base and crashk_size). Since we reserve the memory for the first node, we should be returning from __alloc_bootmem_core() to search for the next node (pg_dat). Currently, find_next_zero_bit() is returning the n^th bit (eidx) when there is no free page. Then, test_bit() is failed since we set 0xff only for the actual size initially (init_bootmem_core()) even though rounded up to one page for bdata->node_bootmem_map. We are hitting the BUG_ON after failing to enter second "for" loop.

由 John McCutchan 提交于
The below patch lets userspace have more control over the inodes that inotify will watch. It introduces two new flags. IN_ONLYDIR -- only watch the inode if it is a directory. This is needed to avoid the race that can occur when we want to be sure that we are watching a directory. IN_DONT_FOLLOW -- don't follow a symlink. In combination with IN_ONLYDIR we can make sure that we don't watch the target of symlinks. The issues the flags fix came up when writing the gnome-vfs inotify backend. Default behaviour is unchanged.

This adds a timestamp field to the events sent via the process event connector. The timestamp allows listeners to accurately account the duration(s) between a process' events and offers strong means with which to determine the order of events with respect to a given task while also avoiding the addition of per-task data. This alters the size and layout of the event structure and hence would break compatibility if process events connector as it stands in 2.6.15-rc2 were released as a mainline kernel.

Commit f549d6c1 introduced a generic fallback for security xattrs, but appears to include a subtle bug. Gentoo users with kernels with selinux compiled in, and coreutils compiled with acl support, noticed that they could not copy files on tmpfs using 'cp'. cp (compiled with acl support) copies the file, lists the extended attributes on the old file, copies them all to the new file, and then exits. However the listxattr() calls were failing with this odd behaviour: llistxattr("a.out", (nil), 0) = 17 llistxattr("a.out", 0x7fffff8c6cb0, 17) = -1 ERANGE (Numerical result out of range) I believe this is a simple problem in the logic used to check the buffer sizes; if the user sends a buffer the exact size of the data, then its ok :) This change solves the problem.

This introduces a new interface - rcu_barrier() which waits until all the RCUs queued until this call have been completed. Reiser4 needs this, because we do more than just freeing memory object in our RCU callback: we also remove it from the list hanging off super-block. This means, that before freeing reiser4-specific portion of super-block (during umount) we have to wait until all pending RCU callbacks are executed. The only change of reiser4 made to the original patch, is exporting of rcu_barrier(). Cc: Hans Reiser <reiser@namesys.com> Cc: Vladimir V.
