ino0 ∈ files, ino ∈ files, ino0 ∈ icache ⊦ ((files ⊕ pcache) ⊕ icache)[ino0] = mkfile (icache[ino0].inode.size, icache[ino0].inode.meta, icache[ino0].inode.nlink, (files ⊕ pcache[datakey(ino, m), mkpentry(true, buf)])[ino0].content), icache[ino0].inode.directory, ino ∈ icache

Additional information

Used simplifier rules: at-icache-overwrite: ⊦ ino ∈ icache ∧ ¬ icache[ino].inode.directory → (files ⊕ icache)[ino] = mkfile (icache[ino].inode.size, icache[ino].inode.meta, icache[ino].inode.nlink, files[ino].content);%at-pcache-overwrite: ⊦ (files ⊕ pcache)[ino] = mkfile (files[ino].size, files[ino].meta, files[ino].nlink, files[ino].content ⊕ mkcontent(ino, pcache));% ⊦ mkfile(m, md, m0, content).content = content; (s)
