Subject[PATCH 0/7] fuse: fix handling mtime and cmtime in writeback_cache mode
From
Date
Hi,

The patch-set fixes a few issues introduced by writeback_cache feature:

- fuse_iget() used inode->i_mode before its initialization
- in course of truncate(2), inode->i_mtime was not updated at all
- the same for open(O_TRUNC) in case of fc->atomic_o_trunc is set
- we cannot trust ctime from server anymore because we doesn't
flush all data changes to the server immediately
- to maintain ctime locally, we have to update it in proper places
(fuse_update_time, fallocate, setxattr, etc.)
- locally updated ctime must be flushed to the server eventually.
