Changes
Since 042stab061.2:
- [drv/tg3] tg3 driver behavior has been reverted to the RHEL's one: tg3 driver does not program MRRS any more, it should be done by node's BIOS. Because of this nodes with not so smart BIOS can face a ~20% network performance degradation. Module option
tg3_pcie_mrrs_boost" has been implemented which forces MRRS to be set to 4Kb (it's max) by tg3 driver which allows workaround for bad BIOSes (PSBM-14240)
- [processes] when CT's init is dying, check if a process is a zombie with the parent outside of this CT and is not collected, kill it. This unblocks CT stop in case there was a vzctl enter + Ctrl-Z (PCLIN-31083)
- [mm] balance between file/anon pressure has been fixed. This prevents the situation when file lru gets much more pressure than anon memory and reclaimer never touches anon pages (PSBM-14619)
- [sysrq] Alt+SysRQ+m has been enhanced to show reclaimer statistics.
- [NFS/lockd/debug] generate a kernel BUG() in case we've got 2 or more identical lock IDs (pids) (debug for PCLIN-31177)
- [ploop] a race in ploop locking has been fixed (PSBM-14751)
