Following bug was uncovered by compiling with '-W' flag:
CC [M] fs/afs/write.o
fs/afs/write.c: In function ‘afs_write_back_from_locked_page’:
fs/afs/write.c:398: warning: comparison of unsigned expression >= 0 is always
true
Loop variable 'n' is unsigned, so wraps around happily as far as I can
see. Trival fix attached (compile tested only).
