53 aio-nr & aio-max-nr
54 -------------------
56 aio-nr is the running total of the number of events specified on the
57 io_setup system call for all currently active aio contexts. If aio-nr
58 reaches aio-max-nr then io_setup will fail with EAGAIN. Note that
59 raising aio-max-nr does not result in the pre-allocation or re-sizing

94 dquot-max & dquot-nr
95 --------------------
97 The file dquot-max shows the maximum number of cached disk
100 The file dquot-nr shows the number of allocated disk quota
108 file-max & file-nr
109 ------------------
111 The value in file-max denotes the maximum number of file-
118 file-nr denote the number of allocated file handles, the number
121 file handles -- this is not an error, it just means that the
125 Attempts to allocate more file descriptors than file-max are
126 reported with printk, look for "VFS: file-max limit <number>

133 This denotes the maximum number of file-handles a process can
139 inode-max, inode-nr & inode-state
140 ---------------------------------
145 The value in inode-max denotes the maximum number of inode
146 handlers. This value should be 3-4 times larger than the value
147 in file-max, since stdin, stdout and network sockets also
151 The file inode-nr contains the first two items from
152 inode-state, so we'll skip to that file...
154 Inode-state contains three actual numbers and four dummies.
