And if I_WILL_FREE is set, then we must not\nincrease nr_unused.  So I believe the above change is buggy and it will\ndefinitely overstate the number of unused inodes and it should be backed\nout.\n\nNote that __writeback_single_inode before calling __sync_single_inode, can\ndrop the spinlock and we can have both the dirty and locked bitflags clear\nhere:\n\n\t\tspin_unlock(\u0026inode_lock);\n\t\t__wait_on_inode(inode);\n\t\tiput(inode);\nXXXXXXX\n\t\tspin_lock(\u0026inode_lock);\n\t}\n\tuse inode again here\n\na construct like the above makes zero sense from a reference counting\nstandpoint.\n\nEither we don\u0027t ever use the inode again after the iput, or the\ninode_lock should be taken _before_ executing the iput (i.e. a __iput\nwould be required). Taking the inode_lock after iput means the iget was\nuseless if we keep using the inode after the iput.\n\nSo the only chance the 2.6 was safe to call __writeback_single_inode\nwith the i_count \u003d\u003d 0, is that I_WILL_FREE is set (I_WILL_FREE will\nprevent the VM to free the inode in XXXXX).\n\nPotentially calling the above iput with I_WILL_FREE was also wrong\nbecause it would recurse in iput_final (the second mainline bug).\n\nThe below (untested) patch fixes the nr_unused accounting, avoids recursing\nin iput when I_WILL_FREE is set and makes sure (with the BUG_ON) that we\ndon\u0027t corrupt memory and that all holders that don\u0027t set I_WILL_FREE, keeps\na reference on the inode!\n\nSigned-off-by: Andrea Arcangeli \u003candrea@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
