Al Viro 4edaeba45b alloc_fdtable(): change calling conventions. ... [ Upstream commit 1d3b4bec3c ] First of all, tell it how many slots do we want, not which slot is wanted. It makes one caller (dup_fd()) more straightforward and doesn't harm another (expand_fdtable()). Furthermore, make it return ERR_PTR() on failure rather than returning NULL. Simplifies the callers. Simplify the size calculation, while we are at it - note that we always have slots_wanted greater than BITS_PER_LONG. What the rules boil down to is * use the smallest power of two large enough to give us that many slots * on 32bit skip 64 and 128 - the minimal capacity we want there is 256 slots (i.e. 1Kb fd array). * on 64bit don't skip anything, the minimal capacity is 128 - and we'll never be asked for 64 or less. 128 slots means 1Kb fd array, again. * on 128bit, if that ever happens, don't skip anything - we'll never be asked for 128 or less, so the fd array allocation will be at least 2Kb.
