Analyze and fix the following issue in the Linux kernel code: x86: Separate out entry text section
Problem Details: Put x86 entry code into a separate link section: .entry.text. Separating the entry text section seems to have performance benefits - caused by more efficient instruction cache usage. Running hackbench with perf stat --repeat showed that the change compresses the icache footprint. The icache load miss...

Analyze and fix the following issue in the Linux kernel code: omfs: merge unlink() and rmdir(), close leak in rename()
Problem Details: In case of directory-overwriting rename(), omfs forgot to mark the victim doomed, so omfs_evict_inode() didn't free it. We could fix that by calling omfs_rmdir() for directory victims instead of doing omfs_unlink(), but it's easier to merge omfs_unlink() and omfs_rmdir() instead. Note that we have no...
