-Subject: [PATCH] pam_tally2: Remove unnecessary fsync()
-
-pam_tally2 does fsync() after writing to a tally file.
-This causes hard drive cache flushes on every failed SSH login on many
-(if not most) filesystems.
-And an internet-exposed machine can have a lot of these failed logins.
-
-This operation however doesn't seem to be necessary - the pam_tally2
-module does not do any operation which would need explicit post-crash
-ordering, it just does simple file reads and writes.
-And doing a fsync() after them doesn't close any race if the system happens
-to crash between a write being posted and its fsync() completion.
-
-Let's remove this operation to get rid of all these extra cache flushes.
