Proof step 2 from proof truncate-empty (previous step)

inode = mkinode(ino, md, false, m, n0, n), pageno = inode.size / VFS_PAGE_SIZE, buf-opt.none?, afs-cons(dirs, files) ⊦ [afs_truncate#(n, pageno; buf-opt, inode, bv, err, dirs, files, asynced)] (err = ESUCCESS → files[ino].content.stream from n = σ⊥)

User applied rule call right

And obtained the following new goals

Proof step 3:
asynced0 ↔ bv, inode = mkinode(ino, md, false, m, n0, n), pageno = inode.size / VFS_PAGE_SIZE, buf-opt.none?, afs-cons(dirs, files) ⊦ [if pre-truncate(inode, n, pageno, buf-opt, dirs, files) then let old_ino0 = 0, old_ino = 0 in afs_truncate_internal#(n, pageno; inode, buf-opt, old_ino0, old_ino, asynced0, err, dirs, files; asynced) else abort] (err = ESUCCESS → files[ino].content.stream from n = σ⊥)

Rule argument

pos: right 1

Additional information

Used simplifier rules: afs_truncate# (N, PAGENO; PBUF-OPT, INODE, MODIFIED, ERR, DIRS, FILES, ASYNCED) {if pre-truncate(INODE, N, PAGENO, PBUF-OPT, DIRS, FILES) then let OFFSET = 0, SIZE = 0 in afs_truncate_internal# (N, PAGENO ; INODE, PBUF-OPT, OFFSET, SIZE, MODIFIED, ERR, DIRS, FILES ; ASYNCED) else abort };
