fuse: add support for SEEK_HOLE and SEEK_DATA through lseek()

2016-02-11T06:16:50+00:00

The Linux FUSE kernel module has gained support for passing SEEK_HOLE
and SEEK_DATA on through lseek(). This can greatly improve performance
when working with sparse files.

Linux FUSE introduced support for lseek() with version 4.5. The commit
in mainline Linux is 0b5da8db145bfd44266ac964a2636a0cf8d7c286.

fuse: update fuse_kernel.h to version 23

2016-02-07T05:56:46+00:00

The following changes were made upstream:
 - add FUSE_WRITEBACK_CACHE
 - add time_gran to fuse_init_out
 - add reserved space to fuse_init_out
 - add FATTR_CTIME
 - add ctime and ctimensec to fuse_setattr_in
 - add FUSE_RENAME2 request
 - add FUSE_NO_OPEN_SUPPORT flag

Including these changes will make it easier to backport support for
lseek().

Because the fuse_init_out structure changed its size, older versions of
FUSE would fail initializing. When an older version of FUSE is detected,
the fuse_init_out structure is reduced to the previous size. This is
harmless, as the attributes that are not passed, are not used for
earlier versions anyway.

fuse: sync fuse_kernel.h from linux 3.11.0(-rc3) header

2013-08-03T12:50:11+00:00

The linux 3.11 fuse kernel header supports up through version 7.22.
Gluster has incrementally supported versions up to 7.22. This is a
hard sync of the most recent kernel header to resolve various,
minor descrepencies and facilitate updates going forward. The
following changes are included:

- Re-typed data structure definitions.
- Missing comments and init flag definitions (i.e., splice).
- Code format and whitespace differences.

No functional changes are included.

fuse-bridge: update to protocol minor version 22

2013-08-03T12:48:44+00:00

7.17
- Distinguishes between POSIX and BSD locking support via a
  separate BSD locking support init flag. Older protocol versions
  (since BSD support was added) export both types of locking
  requests if FUSE_POSIX_LOCKS is specified. Gluster sets this
  flag, so set FUSE_FLOCK_LOCKS as well on kernels that support
  version 17 or newer.

7.18
- Adds ioctl() support for directories (and the associated
  FUSE_IOCTL_DIR flag). Gluster does not support the ioctl
  request, so no changes are required. Update the header.
- Adds support for the delete notification to allow a filesystem
  to inform the kernel of a deleted inode. No gluster changes
  required.

7.19
- Adds support for the fallocate request. Gluster already supports
  fallocate and includes the request opcode definition and data
  structure. Update the header version number.

7.20
- Adds the FUSE_AUTO_INVAL_DATA init flag to enable attribute
  updates on reads and automatic cache invalidation on mtime
  changes. Behavior does not change unless the init flag is
  specified, no gluster changes required. Update header.

7.21
- Adds readdirplus support and updates the poll request to include
  events. Gluster already supports readdirplus and includes the
  relevant data structures. Poll is not supported, so no changes
  are required. Update the header with some missing
  READDIRPLUS_AUTO bits.

7.22
- Adds real asynchronous direct I/O support. Gluster already
  supports/enables the associated bit (FUSE_ASYNC_DIO), no further
  changes are required. Update the header.

fuse-bridge: update to fuse protocol minor version 16 (Linux)

2013-08-02T04:02:26+00:00

7.14
- Splice write support to fuse device node. No gluster changes
  required besides header update.

7.15
- Store/retrieve notification support. No gluster changes
  required besides header update.

7.16
- BATCH_FORGET request support. Implement a handler for
  BATCH_FORGET requests and update the header.
- Updated ioctl() ABI. No gluster changes required besides
  header update.

gluster: add fallocate fop support

2013-06-13T21:37:21+00:00

Implement support for the fallocate file operation. fallocate
allocates blocks for a particular inode such that future writes
to the associated region of the file are guaranteed not to fail
with ENOSPC.

This patch adds fallocate support to the following areas:

	- libglusterfs
	- mount/fuse
	- io-stats
	- performance/md-cache,open-behind
	- quota
	- cluster/afr,dht,stripe
	- rpc/xdr
	- protocol/client,server
	- io-threads
	- marker
	- storage/posix
	- libgfapi

mount/fuse: enable fuse real async dio when available

2013-05-16T00:19:06+00:00

fuse has support for optimized async. direct I/O handling via the
FUSE_ASYNC_DIO init flag. Enable FUSE_ASYNC_DIO when advertised
by fuse.

performance/write-behind: fix dio hang

Also fix a hang observed during aio-stress testing due to conflicting
request handling in write-behind. Overlapping requests are skipped
in pick_winds and may never continue when the conflicting write in
progress returns. Add a wb_process_queue() call after a non-wb request
completes to keep the queue moving.
