Support xcall prefetch.
Changes in v5:
- Fix dentry free before free_prefetch_item() and then UAF in
prefetch work by cancel_work_sync() before free pfi and move
free_prefetch_item() to the first of __fput().
- Fix __queue_work() oops bug.
- /proc/xcall/mask_list -> /proc/xcall/cpu_list
- Fix xcall_prefetch print data type.
- Update prefetch tracepoint, move xcall points definition
to separete header file.
- Make xcall_prefetch depends on EPOLL.
- Adjust xcall prefetch buf to 16KB by default.
- Add xcall_prefetch_init() function.
- Only use write lock in free_prefetch_item().
- Simplify xcall_read() and add some comment.
- Update commit message.
Changes in v4:
- Enable FAST_SYSCALL/IRQ and XCALL_PREFETCH by default.
- Fix xint sleeping function called from invalid context bug.
- free_prefetch_item() in file_free() instead of filp_close(), which
fix the alloc-queue and free competition.
- Fix kernel_read() warning for FMODE_READ not set.
- Add sock_from_file() limit for prefetch.
- Check NULL for rc_work.
- Simplfy the cpumask interface code, and rename
to "/proc/xcall/mask_list".
- Remove the xcall_cache_pages_order interface.
- tracepoint update: fd -> file.
- Simplify the xcall_read() function again.
- Handle copy_to_user() return value.
- Remove unused XCALL_CACHE_QUEUED.
- Update the commit message.
Changes in v3:
- Add XCALL_PREFETCH config to isolate feature code.
- Split the /proc/xxx interface code out to independent patches, which
will make it clear.
- Update the cpumask interface to "/proc/xcall/numa_mask", and it can
set the numa mask of all numas one time.
- Add xcall select count to make xcall_cache_pages_order adjust safe.
- Introduce xcall_read_start/end() to make it clear.
- Simplify the xcall_read() function.
- Use cpumask_next() instead of get_nth_cpu_in_cpumask() function.
- Use independent cpu select policy function.
- Remove some unnecessary pr_err().
- Update the commit message.
Changes in v2:
- Upadte the xcall prefetch state machine, remove the queued state and
add prefetch, cancel states.
- Remove the pfi lock and use atomic variables.
- Change the 'xcall select' semantics and simplify the code a lot.
- Remove keep_running, remove unrelated code.
- Remove the count in struct read_cache_entry, and use
percpu hit/miss count.
- Remove sync mode, so remove struct read_cache_entry
in struct task_struct.
- Use hash table to find prefetch item for a file, which will not
change the file struct KABI.
- Use rwlock instead of spinlock for hash table.
- Use alloc_page() instead kmalloc() to align 4KB.
- Update the commit message.
