There may be a race condition between put an object and
flushing the writecache:
1. Put object to the writecache
2. Writecache flushes object to the blobstore and sets blobstore's
storageID
3. Put object to the metabase, set writecache's storageID

[ #996 ] metabase: Speed up bucket creation
...
Most of the time it exits, e.g. when it is per-container and use on each
object PUT. Bbolt implementation first tries to create bucket and then
returns it if it exists. Create operation uses cursor and thus is not
very lightweight, we can avoid it.

[ #970 ] fstree: Add build tag to enable generic version on linux
...
Unless tested, generic version can start gaining bugs. With a separate
build tag we can have the best of both worlds:
1. Use optimized implementation for linux by default.
2. Run tests or benchmarks for both. Note that they are not actually
run automatically now, but this is at leas possible.

It is not a part of FSTree itself, but rather a way to solve concurrent

is pretty simple: link fails when the file exists, unlink fails when the

[ #970 ] fstree: Add linux-specific file writer using O_TMPFILE
...
O_TMPFILE is implemented for all modern FSes and it's much easier and safer to
use. If application crashes in the middle of writing this file would be gone
and won't leave any garbage.
Notice that this implementation makes a different choice wrt EEXIST handling,
generic one always overwrites, while this one keeps the old data.
There is no real performance difference.
