The elements of the dev->rx.list are consumed in the pending_rx_work and populated in the function enqueue() that cancels the pending_rx_work. The function enqueue() and poison_channel() do not race anyway. Signed-off-by:

The variable is_open is checked only in the work function pending_rx_work() that is only active between the calls configure_channel() and poison_channel(). Signed-off-by:

The real polling rate depends on the CONFIG_HZ and may differ from the required polling rate. Signed-off-by:

This patch avoids that a configured scan_rate of more than MSEC_PER_SEC might result in a polling delay of zero. Signed-off-by:

Currently the IRQ handler used for the rx channel lives between the functions i2c_probe and i2c_remove. This patch shortens the lifetime and keeps the handler alive only between the functions configure_channel and poison_channel. Signed-off-by:

Currently, the only supported PCM formats are 1x8", "2x16", "2x24", "2x32" or "6x16". This adds support for the format "Nx{8,16,24,32}" that also includes the exotic PCM formats like "4x16", "5x8", etc. Signed-off-by: -

This prevents division by zero scan_rate. The zero scan_rate does not need any special action as it actually means "never poll again". Signed-off-by:

This removes the module parameter clock_speed from the HDM code. Instead, the platform-dependent clock speed must be delivered by the platform driver with the help of the dim2_platform_data.clk_speed. Signed-off-by:

This prohibits the allocation of the memory for the MBOs if only the part of the MBOs, requested by the application, may be allocated. The function arm_mbo_chain, if cannot allocate all requested MBO, frees all prior allocated memory and returns 0. Signed-off-by:

d_splice_alias() can return an ERR_PTR(). If it does while debugging is enabled, the following CDEBUG() will dereference that error and crash. So add appropriate checking, and provide a separate debug message for the error case. Reported-and-tested-by:

The ioctl handler for the misc device is in lnet/libcfs/module.c but is it registered in lnet/libcfs/linux/linux-module.c. Keeping related code together make maintenance easier, so move the code. Reviewed-by:

Both the 'next' and the 'show' functions for the dump_page_cache seqfile perform a lookup based on the current file index. This is needless duplication. The reason appears to be that the state that needs to be communicated from "next" to "show" is two pointers, but seq_file only provides for a single pointer to be returned from next and passed to show. So make use of the new 'seq_private' structure to store the extra pointer. So when 'next' (or 'start') find something, it returns the page and stores the clob in the private area. 'show' accepts the page as an argument, and finds the clob where it was stored. Signed-off-by:

The dump_page_cache debugfs file allocates and frees an 'env' in each call to vvp_pgcache_start,next,show. This is likely to be fast, but does introduce the need to check for errors. It is reasonable to allocate a single 'env' when the file is opened, and use that throughout. So create 'seq_private' structure which stores the sbi, env, and refcheck, and attach this to the seqfile. Then use it throughout instead of allocating 'env' repeatedly. Signed-off-by:

lu_object_new() duplicates a lot of code that is in lu_object_find_at(). There is no real need for a separate function, it is simpler just to skip the bits of lu_object_find_at() that we don't want in the LOC_F_NEW case. Signed-off-by:

The current retry logic, to wait when a 'dying' object is found, spans multiple functions. The process is attached to a waitqueue and set TASK_UNINTERRUPTIBLE in htable_lookup, and this status is passed back through lu_object_find_try() to lu_object_find_at() where schedule() is called and the process is removed from the queue. This can be simplified by moving all the logic (including hashtable locking) inside htable_lookup(), which now never returns EAGAIN. Note that htable_lookup() is called with the hash bucket lock held, and will drop and retake it if it needs to schedule. I made this a 'goto' loop rather than a 'while(1)' loop as the diff is easier to read. Signed-off-by:

lu_object maintains 2 lru counts. One is a per-bucket lsb_lru_len. The other is the per-cpu ls_lru_len_counter. The only times the per-bucket counters are use are: - a debug message when an object is added - in lu_site_stats_get when all the counters are combined. The debug message is not essential, and the per-cpu counter can be used to get the combined total. So discard the per-bucket lsb_lru_len. Reviewed-by:

This data structure only needs to be public so that various modules can access a wait queue to wait for object destruction. If we provide a function to get the wait queue, rather than the whole bucket, the structure can be made private. Reviewed-by:

Code currently defines: #define CONFIG_PCIE_PORT0 #define CONFIG_PCIE_PORT1 #define CONFIG_PCIE_PORT2 #define GPIO_PERST and then compiles code only if they are defined. We might want to disable some of these via devicetree one day, but for now just remove the #defines and the conditions - all the code for different ports is easy to identify. Signed-off-by:
