Subject: [lttng-dev] [PATCH lttng-modules v5 0/5] Extract payload from
	polling syscalls
Message-ID: <1461370612-15264-1-git-send-email-jdesfossez@efficios.com>

Patch serie to extract the payload of the polling system calls on x86 and ARM
(32 and 64-bit). The concerned system calls are select, pselect6, poll, ppoll,
epoll_ctl, epoll_wait, epoll_pwait.

Changes from v4:
 - Use GFP_ATOMIC memory for dynamic allocation (because we cannot sleep in TP)
 - Limit the allocated memory to one page
 - Set an overflow flag if we cannot allocate enough memory
 - Fix endianness problem for select
 - Bugfix from v4 review

Changes from v3:
 - Use dynamic allocation for select
 - Bugfix from v3 review
 - Cleanup epoll_wait error handling

Changes from v2:
 - Make sure all user-controlled data is handled safely in the kernel
 - Allocate memory instead of using the stack for arbitrarily large data
 - Only extract the standard event flags and output the raw event value as hex
 - Various bugfixes from v2

Julien Desfossez (5):
  Add ctf_integer_bitfield_type
  Extract the FD sets in select and pselect6
  Extract the FDs and flags from poll and ppoll
  Extract the payload for epoll_ctl
  Extract the payload of epoll_wait/epoll_pwait
