Analyze and fix the following issue in the Linux kernel code: ext2: Fix link count corruption under heavy link+rename load
Problem Details: vfs_rename_other() does not lock renamed inode with i_mutex. Thus changing i_nlink in a non-atomic manner (which happens in ext2_rename()) can corrupt it as reported and analyzed by Josh. In fact, there is no good reason to mess with i_nlink of the moved file. We did it presumably to simulate linking ...

Analyze and fix the following issue in the Linux kernel code: iwlagn: fix iwlagn_check_needed_chains
Problem Details: This function was intended to calculate the number of RX chains needed, but could only work where the AP's streams were asymmetric, i.e. 2 TX and 3 RX or similar. In the case where IEEE80211_HT_MCS_TX_RX_DIFF was not set, this function would calculate the wrong information. Additionally, mac80211 didn...
