Hmm I'm getting this compiler warning: fs/ext4/inode.c: In function ‘ext4_writepages’: fs/ext4/inode.c:2219:6: warning: ‘err’ may be used uninitialized in this function [-Wmaybe-uninitialized]
and I think the compiler is right to warn. The 'err' variable is set inside a whilte() and an if() statement, and it is not at all obvious that those codepaths are always taken. Maybe that "map->m_len" is always guaranteed to be nonzero, and the "while()" statement could be a "do { } while()" one. But if so, make it so, don't write code as if it might never be executed, when the return value seems to *depend* on it being executed. Or just initialize the variable correctly. This warning may not be new to this pull, I just happened to notice it now.
