Subject: fuse: don't use inode in fuse_file_poll
X-Git-Tag: v2.6.31-rc1~370^2~3
X-Git-Url: http://ftp.safe.ca/?p=safe%2Fjmp%2Flinux-2.6;a=commitdiff_plain;h=797759aaf31351a1ab1b9130c4f180ce496f46c5

fuse: don't use inode in fuse_file_poll

Use ff->fc and ff->nodeid instead of file->f_dentry->d_inode in the
fuse_file_poll() implementation.

This prepares this function for use by CUSE, where the inode is not
owned by a fuse filesystem.
