mount/fuse: perform lookup() on inodes linked through readdirplus

2013-09-10T00:19:09+00:00

Some xlators still require lookup() fop to be sent for proper working.
This patch remembers inodes which have been linked through readdiprlus
and makes the resolver send lookups on them.

Also, introduce and use context count for inode table.

md-cache: invalidate attributes on xattr update

2013-09-08T13:59:02+00:00

xattr update will result in at least ctime change. So invalidate
attributes in xattr callback.

md-cache: support negative xattr entries

2013-06-08T21:50:34+00:00

Add support for negative xattr caching. For this, we need
to fetch xattrs in every opportunity (including readdirplus)
in order to treat missing key in cached dict as negative entry.

This is crucial to detect missing ACL xattrs in Samba workload.

performance/md-cache: add force-readdirp flag to make readdirp configurable

2013-01-29T01:26:37+00:00

md-cache currently transforms all readdir fops into readdirp fops.
This patch creates the 'force-readdirp' configuration flag to
provide control over this behavior. force-readdirp is enabled by
default to maintain current default behavior.

* ie, don't dereference dict_t pointer, instead use APIs everywhere

fuse/md-cache: add support for the 'fopen-keep-cache' mount option

2012-07-13T16:46:09+00:00

fopen-keep-cache disables unconditional page-cache invalidations
on file open in fuse (via FOPEN_KEEP_CACHE) and replaces that
behavior with detection of remote changes and explicit
invalidations from mount/fuse. This option improves local caching
through the page cache and native client.

This change defines a new 'invalidate' translator callback to
identify when an inode's cache mapping has been determined to be
invalid. md-cache implements the policy to detect and invoke
inode invalidations. fuse-bridge and io-cache implement
invalidate handlers to invalidate the respective caches (page
cache in the case of fuse).
