| |
Hi,
Andrew, would you consider including this patchset in -mm for some more testing. At least patches 1 - 4.
Patch 5 is the new listio syscall approach from Bharata B Rao which is much cleaner than overloading sys_io_submit() with a new opcode but maybe needs some more discussion before being engraved in stone.
I'm thinking here of having the capability to be notified when m requests have completed (m <= total_number_of_submitted_requests) as suggested by Ulrich Drepper.
Ulrich, is this still something you want? In which case we may need to add another argument to sys_lio_submit().
Sébastien.
This set consists in 5 patches:
1. rework-compat-sys-io-submit: cleanup the sys_io_submit() compat layer, making it more efficient and laying out the base for the following patches
2. aio-header-fix-includes: fixes the double inclusion of uio.h in aio.h
3. export-good_sigevent: move good_sigevent into signal.c and make it non-static
4. aio-notify-sig: the AIO completion signal notification
5. listio: adds listio support
Description are in the individual patches.
Changes from v4: No comments received for v4, so it must be perfect ;-) replaced the IOCB_CMD_GROUP listio implementation with Bharata's syscall approach which I find much cleaner.
Changes from v3: All changes following comments from Zach Brown and Christoph Hellwig
- added justification for the compat_sys_io_submit() cleanup - more cleanups in compat_sys_io_submit() to put it in line with sys_io_submit() - Changed "Export good_sigevent()" patch name to "Make good_sigevent() non-static" to better describe what it does.=20 - Reworked good_sigevent() to make it more readable. - Simplified the use of the SIGEV_* constants in signal notification - Take a reference on the target task both for the SIGEV_THREAD_ID and SIGEV_SIGNAL cases.
Changes from v2: - rebased to 2.6.19-rc6-mm2 - reworked the sys_io_submit() compat layer as suggested by Zach Brown - fixed saving of a pointer to a task struct in aio-notify-sig as pointed out by Andrew Morton
Changes from v1: - cleanups suggested by Christoph Hellwig, Badari Pulavarty and Zach Brown - added listio patch - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
