Based on the previous posting discussion, i_readcount is now defined as atomic. This patchset separates the incrementing/decrementing of the i_readcount, in the VFS layer, from other IMA functionality, by replacing the current ima_counts_get() call with iget_readcount(). Its unclear whether this call to increment i_readcount should be made earlier, like i_writecount. The patch ordering is a bit redundant in order to leave removing the ifdef around i_readcount until the last patch. The first four patches: redefines i_readcount as atomic, defines iget/iput_readcount(), moves the IMA functionality in ima_counts_get() to ima_file_check(), and removes the IMA imbalance code, simplifying IMA. The last patch moves iput_readcount() to the fs directory and removes the ifdef around i_readcount, making i_readcount into a "first class inode citizen". The generic_setlease code could then take advantage of i_readcount.
