fs/affs: bugfix: make symbolic links work again
AFFS symbolic links were broken since kernel 2.6.29
Problem was bisected to the following
commit ebd09abbd969 ("vfs: ensure page symlinks are NUL-terminated")
commit 035146851cfa ("vfs: introduce helper function to safely
NUL-terminate symlinks")
AFFS wasn't setting inode size when reading symbolic link from disk or
creating a new one. Result was zero allocation in pagecache.
ln -s file symlink
ls -lrt
file
symlink ->
This patch adds inode isize information on inode get and symbolic link
addition.
