2011-03-03ceph: do not clear I_COMPLETE from d_releaseSage Weil1-21/+1
First, this was racy anyway: d_release isn't called until well after the dentry is unhashed. Second, this runs afoul of the recent dcache change that clears d_parent prior to calling d_release (949854d0), causing a NULL pointer dereference. Signed-off-by: Sage Weil <[email protected]>

2011-03-03Revert "ceph: keep reference to parent inode on ceph_dentry"Sage Weil2-5/+1
This reverts commit 97d79b403ef03f729883246208ef5d8a2ebc4d68. This fails to account for d_parent changes due to rename or disconnected dentries due to submounts or NFS reexports. Signed-off-by: Sage Weil <[email protected]>
2011-03-03[S390] tape: deadlock on system work queueMartin Schwidefsky3-34/+116
The 34xx and 3590 tape driver uses the system work queue to defer work from the interrupt function to process context, e.g. a medium sense after an unsolicited interrupt. The tape commands started by the work handler need to be asynchronous, otherwise a deadlock on the system work queue can occur. Signed-off-by: Martin Schwidefsky <[email protected]>
2011-03-03[S390] keyboard: integer underflow bugDan Carpenter1-1/+2
The "ct" variable should be an unsigned int. Both struct kbdiacrs ->kb_cnt and struct kbd_data ->accent_table_size are unsigned ints. Making it signed causes a problem in KBDIACRUC because the user could set the signed bit and cause a buffer overflow.

The module parameter 'devs' and 'sizes' are marked as __initdata. The memory for the parameters are freed after module_init completed. This can lead to kernel crashes in param_free_charp. Remove the __initdata attribute to fix the problem. Signed-off-by: Martin Schwidefsky <[email protected]>

2011-03-03blktrace: Remove blk_fill_rwbs_rq.Tao Ma3-20/+3
If we enable trace events to trace block actions, We use blk_fill_rwbs_rq to analyze the corresponding actions in request's cmd_flags, but we only choose the minor 2 bits from it, so most of other flags(e.g, REQ_SYNC) are missing. For example, with a sync write we get: write_test-2409 [001] 160.013869: block_rq_insert: 3,64 W 0 () 258135 + = 8 [write_test] Since now we have integrated the flags of both bio and request, it is safe to pass rq->cmd_flags directly to blk_fill_rwbs and blk_fill_rwbs_rq isn't needed any more. With this patch, after a sync write we get: write_test-2417 [000] 226.603878: block_rq_insert: 3,64 WS 0 () 258135 += 8 [write_test] Signed-off-by: Tao Ma <[email protected]> Acked-by: Jeff Moyer <[email protected]> Signed-off-by: Jens Axboe <[email protected]>
2011-03-03ALSA: hda - Don't set to D3 in Cirrus errata init verbsTakashi Iwai1-0/+2
The errata init verbs for CS42xx codecs contain the verbs to set the power-state of SPDIF nodes to D3, which seem to break the SPDIF output on some MacBooks. Since this is executed during the power-up initialization, we shouldn't turn them down there.

if directory has so many subdirectories that its link count is set to 1 (i.e. "can't tell accurately") and reiserfs_new_inode() fails, we shouldn't decrement the parent's link count in cleanup path; that's what DEC_DIR_INODE_NLINK() is for. As it is, we end up with parent suddenly getting zero i_nlink, with very unpleasant effects. Signed-off-by: Al Viro <[email protected]>

2011-03-02RxRPC: Fix v1 keysAnton Blanchard1-1/+0
commit 339412841d7 (RxRPC: Allow key payloads to be passed in XDR form) broke klog for me. I notice the v1 key struct had a kif_version field added: -struct rxkad_key { - u16 security_index; /* RxRPC header security index */ - u16 ticket_len; /* length of ticket[] */ - u32 expiry; /* time at which expires */ - u32 kvno; /* key version number */ - u8 session_key[8]; /* DES session key */ - u8 ticket[0]; /* the encrypted ticket */ -}; +struct rxrpc_key_data_v1 { + u32 kif_version; /* 1 */ + u16 security_index; + u16 ticket_length; + u32 expiry; /* time_t */ + u32 kvno; + u8 session_key[8]; + u8 ticket[0]; +}; However the code in rxrpc_instantiate strips it away: data += sizeof(kver); datalen -= sizeof(kver); Removing kif_version fixes my problem.

We service 2 queues (kcq1 and kcq2) in cnic_service_bnx2x_bh(). If the status block index has changed when servicing the kcq2, we must go back and check kcq1. The latest status block index will be used to acknowledge the interrupt, and without looping back to check kcq1, we may miss events on kcq1.

2011-03-02of/promtree: allow DT device matching by fixing 'name' brokenness (v5)Andres Salomon1-70/+42
Commit e2f2a93b, "of/promtree: add package-to-path support to pdt" changed dp->name from using the 'name' property to using package-to-path. This fixed /proc/device-tree creation by eliminating conflicts between names (the 'name' property provides names like 'battery', whereas package-to-path provides names like '/foo/bar/battery@0', which we stripped to 'battery@0'). However, it also breaks of_device_id table matching. The fix that we _really_ wanted was to keep dp->name based upon the name property ('battery'), but based dp->full_name upon package-to-path ('battery@0'). This patch does just that. This changes all users (except SPARC) of promtree to use the full result from package-to-path for full_name, rather than stripping the directory out. In practice, the strings end up being exactly the same; this change saves time, code, and memory. SPARC continues to use the existing build_path_component() code. v2: combine two patches and revert of_pdt_node_name to original version v3: use dp->phandle instead of passing around node v4: warn/bail out for non-sparc archs if pkg2path is not set v5: split of_pdt_build_full_name into sparc & non-sparc versions v6: Pass NULL to pkg2path before buf gets assigned. Drop check for pkg2path hook on each and every node. v7: Don't BUG() when unable to get the full_path; create a known-unique name instead.
