This fixes a bug whereby if two processes try to look up the same auth_gss credential, they may end up creating two creds, and triggering two upcalls because the upcall is performed before the credential is added to the credcache. Signed-off-by:Trond Myklebust <Trond.Myklebust@netapp.com>

The function rpc_timeout_upcall_queue runs from a workqueue, and hence sleeping is not recommended. Convert the protection of the upcall queue from being mutex-based to being spinlock-based. Signed-off-by: -

When we look up a new cred in the auth_gss downcall so that we can stuff the credcache, we do not want that lookup to queue up an upcall in order to initialise it. To do an upcall here not only redundant, but since we are already holding the inode->i_mutex, it will trigger a lock recursion. This patch allows rpcauth cache searches to indicate that they can cope with uninitialised credentials. Signed-off-by: -

If the server returns NLM_LCK_DENIED_NOLOCKS, we currently retry the entire NLM_CANCEL request. This may end up looping forever unless the server changes its mind (why would it do that, though?). Ensure that we limit the number of retries (to 3). See bug# 5957 in bugzilla.kernel.org. Signed-off-by: -

The OpenGroup docs state that the arguments "block", "exclusive" and "alock" must exactly match the arguments for the lock call that we are trying to cancel. Currently, "block" is always set to false, which is wrong. See bug# 5956 on bugzilla.kernel.org. Signed-off-by: -

Some time before 2.6.15, a third DDC channel was added to i810fb. On systems where these ddc pins are not connected, the probe takes about 10 seconds. Add a boot/module option for i810fb to explicitly probe for the 3rd ddc bus if needed. Signed-off-by:

reiserfs: journal_transaction_should_end should increase the count of blocks allocated so the transaction subsystem can keep new writers from creating a transaction that is too large. Signed-off-by:

write_ordered_buffers should handle dirty non-uptodate buffers without a BUG() Signed-off-by:
-
Chris Mason authored
In data=journal mode, reiserfs writepage needs to make sure not to trigger transactions while being run under PF_MEMALLOC. This patch makes sure to redirty the page instead of forcing a transaction start in this case. Also, calling filemap_fdata* in order to trigger io on the block device can cause lock inversions on the page lock. Instead, do simple batching from flush_commit_list. Signed-off-by:

The b_private field in buffer heads needs to be zero filled when the buffers are allocated. Thanks to Nathan Scott for finding this. It was causing problems on systems with both XFS and reiserfs. Signed-off-by:

After a transaction has closed but before it has finished commit, there is a window where data=ordered mode requires invalidatepage to pin pages instead of freeing them. This patch fixes a race between the invalidatepage checks and data=ordered writeback, and it also adds a check to the reiserfs write_ordered_buffers routines to write any anonymous buffers that were dirtied after its first writeback loop. That bug works like this: proc1: transaction closes and a new one starts proc1: write_ordered_buffers starts processing data=ordered list proc1: buffer A is cleaned and written proc2: buffer A is dirtied by another process proc2: File is truncated to zero, page A goes through invalidatepage proc2: reiserfs_invalidatepage sees dirty buffer A with reiserfs journal head, pins it proc1: write_ordered_buffers frees the journal head on buffer A At this point, buffer A stays dirty forever Signed-off-by: -

Remove useless s390 define from hangcheck-timer, remove wrong definition of a TOD second and other s390 ifdefs. Use monotonic_clock instead. Add hangcheck-timer option, copied from drivers/char/Kconfig. This is ugly but unless we have a big Kconfig cleanup we cannot include drivers/char/Kconfig... Signed-off-by:

Add monotonic_clock interface, used by the hangcheck-timer. On s390 this is the same as sched_clock(). Signed-off-by:

Jan Glauber authored
The least significant bit of the TOD clock value returned by get_clock is the 4096th part of a microsecond. To get to nanoseconds the value needs to be divided by 4096 and multiplied with 1000. The current method multiplies first and then shifts the value to make the result as precise as possible. The disadvantage is that the multiplication with 1000 will overflow shortly after 52 days. sched_clock is used by the scheduler for time stamp deltas, if an overflow occurs between two time stamps the scheduler will get confused. With the patch the problem occurs only after approx. one year, so the chance to run into this overflow is extremly low. Signed-off-by:
