[PATCH] fuse: do not evict dirty inodes
From: Maxim Patlasov
Date: Tue Jun 03 2014 - 07:49:30 EST
Commit 1e18bda8 added .write_inode method to the fuse super_operations. This
allowed fuse to use the kernel infrastructure for writing out dirty metadata
(mtime and ctime for now). However, given that .drop_inode was not redefined
from the legacy generic_delete_inode(), on umount(2) generic_shutdown_super()
led to the eviction of all inodes disregarding their state.
The patch removes .drop_inode definition from the fuse super_operations. This
works because now iput_final() calls generic_drop_inode() and returns w/o
evicting inode. This, in turn, allows generic_shutdown_super() to write dirty
inodes by calling sync_filesystem().
