utime: ctime client side xlator

2018-05-06T01:39:18+00:00

The client side utime xlator does two things.

1. Update unix epoch time in frame->root->ctime
2. Update the frame->root->flags based on the fop
   which indicates time attributes that should be
   updated for the parent/entry.

posix/ctime: posix hook to set ctime xattr in relevant fops

2018-05-06T01:39:08+00:00

This patch uses the ctime posix APIs to set consistent
time across replica on disk. It also stores the time
attributes in the inode context.

posix/ctime: posix hooks to get consistent time xattr

2018-05-06T01:36:53+00:00

This patch uses the ctime posix APIs to get consistent
time across replica. The time attributes are got from
from inode context or from on disk if not found and
merged with iatt to be returned.

posix: APIs in posix to get and set time attributes

2018-05-06T01:32:30+00:00

This is part of the effort to provide consistent time
across distribute and replica set for time attributes
(ctime, atime, mtime) of the object. This patch contains
the APIs to set and get the attributes from on disk
and in inode context.

fuse: add support for kernel writeback cache

2018-05-04T17:42:12+00:00

- Added kernel-writeback-cache command line and xlator
  option for requesting utilisation of the writeback
  cache of the kernel in FUSE_INIT (see [1]).
- Added attr-times-granularity command line and xlator
  option via which granularity of the {a,m,c}time in
  stat (attr) data that we support can be indicated to
  kernel. This is a means to avoid divergence of the
  attr times between kernel and userspace that could
  occur with writeback-cache, while still maintaining
  maximum time precision the FUSE server is capable of
  (see [2]).
- Handling FATTR_CTIME flag in FUSE_SETATTR that
  indicates presence of ctime in setattr payload.
  Currently we cannot associate arbitrary ctimes to
  files on backend, so we just touch them to update
  their ctimes to current time. Having ctimes in setattr
  payload is also a side effect of writeback cache
  (see [3] and [4]).
