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: -

The sleep_on function clears a running cqr without waiting for the related interrupt. This can lead to a panic at the time the interrupt is processed because the related memory might already be freed. Wait for clear-interrupt and de-queue cqr prior to return. Signed-off-by:

The return code of ccw_device_probe_console() is not properly handled. It should only return a valid ccw device pointer or a error value converted by ERR_PTR. Fix the console driver code to check with IS_ERR instead against NULL. 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:

Olaf Hering <olh@suse.de> Olaf reported UML doesn't build for him with a clear analisys of what happened - we're using NR_CPUS in files linked against glibc headers. Seems like it defines CONFIG_SMP but not CONFIG_NR_CPUS, so we get CONFIG_NR_CPUS undeclared. The fix is to move the declaration away from that header file and move it in asm-um headers, and to add that header where needed.

In a recent fixup i386 code was copied raw to x86_64 subarch to make it compile again. Here there are some little fixups and resyncs needed for it (mainly for cleanliness sake) - I did an audit and found the rest of the code to be safe. Signed-off-by:

Fixes a bug introduced in commit e32dacb9 - index is initialized based on syscall before syscall is calculated. I'm bothering with this mainly because it gives a correct warning when the config option is enabled, even if the code is for a almost unused debugging option. Signed-off-by:

The C99 initialization, with GCC's bad handling, for 6K wide structs (which _aren't_ on the stack), is causing GCC to use 12K for these silly procs with 3 vars. Workaround this. Note that .name = { '\0' } translates to memset(->name, 0, '->name' size) - I verified this with GCC's docs and a testprogram. Signed-off-by: -
