* ARM: common: edma: clear completion interrupts on stopJohn Ogness2015-05-061-0/+3
| | | | | | | | | | | | | | When stopping a DMA transfer with interrupts disabled it is possible that the DMA transfer completes before the events are cleared. In this case the completion interrupt will be pending, causing a completion callback after the transfer was stopped. By clearing the completion interrupt for the stopping channel it is ensured that no completion event will be generated after the stop.

| | | | | | | | | | | | | | | | | | Commit 734745c serial/amba-pl011: Activate TX IRQ passively adds some complexity and overhead in the form of a softirq mechanism for transmitting in the absence of interrupts. This patch simplifies the code flow to reduce the reliance on subtle behaviour and avoid fragility under future maintenance. To this end, the TX softirq mechanism is removed and instead pl011_start_tx() will now simply stuff the FIFO until full (guaranteeing future TX IRQs), or until there are no more chars to write (in which case we don't care whether an IRQ happens).

| | | | | | | | | | | | | | | | | | | This reverts commit f2ee6dfa0e8597eea8b98d240b0033994e20d215. Jakub Kiciński observed that this patch can cause the pl011 driver to hang if if the only process with a pl011 port open is killed by a signal, pl011_shutdown() can get called with an arbitrary amount of data still in the FIFO. Calling _shutdown() with the TX FIFO non-empty is questionable behaviour and my itself be a bug. Since the affected patch was speculative anyway, and brings limited benefit, the simplest course is to remove the assumption that TXIS will always be left asserted after the port is shut down.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The estimate of necessary transaction credits in ext4_flex_group_add() is too pessimistic. It reserves credit for sb, resize inode, and resize inode dindirect block for each group added in a flex group although they are always the same block and thus it is enough to account them only once. Also the number of modified GDT block is overestimated since we fit EXT4_DESC_PER_BLOCK(sb) descriptors in one block. Make the estimation more precise. That reduces number of requested credits enough that we can grow 20 MB filesystem (which has 1 MB journal, 79 reserved GDT blocks, and flex group size 16 by default).

The problem is that when we insert delayed extent into extent status tree the only way to get rid of it is when we write out delayed buffer. However there is a limitation in the extent status tree implementation so that when inserting unwritten extent should there be even a single delayed block the whole unwritten extent would be marked as delayed. At this point, there is no way to get rid of the delayed extents, because there are no delayed buffers to write out. So when a we write into said unwritten extent we will convert it to written, but it still remains delayed. When we try to write into that block later ext4_da_map_blocks() will set the buffer new and delayed and map it to invalid block which causes the rest of the block to be zeroed loosing already written data. For now we can fix this by simply not allowing to set delayed status on written extent in the extent status tree. Also add WARN_ON() to make sure that we notice if this happens in the future. This problem can be easily reproduced by running the following xfs_io. xfs_io -f -c "pwrite -S 0xaa 4096 2048" \ -c "falloc 0 131072" \ -c "pwrite -S 0xbb 65536 2048" \ -c "fsync" /mnt/test/fff echo 3 > /proc/sys/vm/drop_caches xfs_io -c "pwrite -S 0xdd 67584 2048" /mnt/test/fff This can be theoretically also reproduced by at random by running fsx, but it's not very reliable, though on machines with bigger page size (like ppc) this can be seen more often (especially xfstest generic/127) Signed-off-by: Lukas Czerner <lczerner@redhat.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu> Cc: stable@vger.kernel.org
