Updated kernel packages that fix several bugs are now available for Red HatEnterprise Linux 6.6 Extended Update Support.
The kernel packages contain the Linux kernel, the core of any Linuxoperating system.This update also fixes the following bugs:* When removing a directory and a reference was held to that directory by areference to a negative child dentry, the directory dentry was previously notkilled.
In addition, once the negative child dentry was killed, unlinked andunused dentry was present in the cache.

As a consequence, deadlock could becaused by forcing the dentry eviction while the file system in question wasfrozen. With this update, all unused dentries are unhashed and evicted justafter a successful directory removal, which avoids the deadlock, and the systemno longer hangs in the aforementioned scenario. (BZ#1282620)* Previously, unusual forking pattern could cause the anon_vma_chain andanon_vma slab memory to grow infinitely even though the number of processesinvolved stayed low.

As a consequence, a kernel panic occurred.

The providedpatch adds a heuristic which reuses existing anon_vma instead of forking a newone and adds the anon_vma->degree counter which makes sure the count ofanon_vmas is not bigger than twice the count of vmas.

As a result, the kernelpanic no longer occurs in this situation. (BZ#1285692)* Due to a race condition, the journal_remove_journal_head() function couldpreviously oops when trying to access journal_head returned by the bh2jh()function.

This update provides an upstream patch fixing this oops. (BZ#1291346)* Due to a timer expiry issue, the scheduler tick previously stopped for toolong when the ksoftirqd daemon for hrtimer was blocked by a running process.This update adds the force_hrtimer_reprogram kernel parameter.
Ifforce_hrtimer_reprogram=1 is used on the kernel command line, the reprogrammingof all expired timers is forced, which prevents this bug. (BZ#1292081)* Resetting an ixgbe or vmxnet3 adapter while sending a message over netconsoleor netpoll at the same time could previously cause a kernel crash.

This updateadds mutual exclusion between the core adapter reset path and netpoll transmitpath, preventing kernel crashes in this situation.(BZ#1295368)Users of kernel are advised to upgrade to these updated packages, which fixthese bugs.

The system must be rebooted for this update to take effect.
