xfs-5.9-fixes-1
125eac24 · ·Fixes for 5.9: - Avoid a log recovery failure for an insert range operation by rolling deferred ops incrementally instead of at the end. - Fix an off-by-one error when calculating log space reservations for anything involving an inode allocation or free. - Fix a broken shortform xattr verifier. - Ensure that the shortform xattr header padding is always initialized to zero.

x86-urgent-2020-08-23
6a3ea3e6 · ·A single fix for x86 which removes the RDPID usage from the paranoid entry path and unconditionally uses LSL to retrieve the CPU number. RDPID depends on MSR_TSX_AUX. KVM has an optmization to avoid expensive MRS read/writes on VMENTER/EXIT. It caches the MSR values and restores them either when leaving the run loop, on preemption or when going out to user space. MSR_TSX_AUX is part of that lazy MSR set, so after writing the guest value and before the lazy restore any exception using the paranoid entry will read the guest value and use it as CPU number to retrieve the GSBASE value for the current CPU when FSGSBASE is enabled. As RDPID is only used in that particular entry path, there is no reason to burden VMENTER/EXIT with two extra MSR writes. Remove the RDPID optimization, which is not even backed by numbers from the paranoid entry path instead.
