ChangesEdit

[fs/capabilities] ltp testcase failed cause it was unable to set our new internal capability CAP_FS_FREEZE. Fixed this (PCLIN-31607)
[fs/nfsd] fixed mnt_{get/drop} balance, the imbalance could cause random memory corruptions (#2506)
[sunrpc] forgotten socket write lock in case rpc_task exists early, this caused all operations on NFS volume to hang (PCLIN-31604)
[tmpfs] avoid the crash by not releasing the mempolicy if shmem_parse_options() doesn't create a new mpol by remounting without mpol= mount option (PSBM-18650)
[ext4] container should not be able to remount ploop with mount option 'errors=panic'
[fs] forbid filesystem mount options (on remount inside a CT) if white list was not provided
[cpt] 64bit child process of 32bit parent should report x86_64 arch even after vzreboot/online migration. This fixes Plesk functioning in particular after vzreboot/online migration (PSBM-18085)
[cpt] if parent process has PER_LINUX32 and child has 0, it should stay the same way after cpt/rst. Before this fix cpt/rst cycle made PER_LINUX32 in both processes
[pfcache] hide mount options 'pfcache_csum' and 'pfcache' inside a CT. They are useless inside a CT anyway and produces kernel warnings on remounts (PSBM-18807)
[nfs/quota] fixed crash on a kernel compiled without NFS quota
[scheduler] the effective cpulimit could be sometimes lower than assigned (PSBM-17399)
